Alum Q&A: Kathleen Watt ’11
Kathleen Watt works for Insurance Brokerage Firm in New York City. Katie was a Mathematic major, Class of 2011
What made you interested in studying mathematics at Northeastern? Why do you believe this is a great choice for a major?
“I am a little bit different in that I went into college searches knowing that I wanted to be an actuary. I really liked math and I knew it was something I wanted to study in college. When I had done preliminary research on what careers there were for mathematics majors, teaching always came up as a popular option, but that wasn’t something I was interested in pursuing. During the various college information sessions I attended, I realized I wasn’t 100% confident that I wanted to become an actuary. When I found Northeastern and learned about their co-op program, it seemed like a great option to explore what I wanted to do. The co-op program was the reason I chose math specifically at Northeastern. I think there are so many different opportunities and ways you can use your math degree which makes it a very flexible major.”
What opportunities can you pursue as a mathematics major?
“A lot of people I went to college with pursued teaching and did the five -year PlusOne
master’s program at Northeastern. Many also go on to graduate work: getting a master’s or PhD. There is a lot of coding or heavy data analysis which can lead towards the actuarial side. Some classmades went onto completely different careers such as law school or engineering programs because at the end of the day, math teaches you how to think and to problem-solve which is useful in so many skill sets.”
Are there any specific memories from your time at Northeastern that had a lasting impact on you? Any that influenced your career choices?
“Northeastern is where I made some of my best friends and where I grew into myself. It was also the first time I lived in a major city and used public transportation on an every day basis. From that perspective, Northeastern gave me the opportunities to experience all of these things and decide how I wanted to shape my lifestyle. All three co-ops helped me learn about the working world and what I would and wouldn’t want from a career path.”
While attending Northeastern, you completed three co-ops. How did each of your co-op experiences impact your career choices?
“As I said, I thought I wanted to be an actuary and live in a big city, so my first co-op was a dream come true from the perspective that I lived and worked in New York City. It was during during the financial crisis of 2008, so it was an eye-opening experience to be in an office and see those who work around you lose their jobs. It was a dose of reality on multiple levels to learn that it’s a business and you have to do what is best for you because companies will do what’s best for them. My second co-op was in the public sector because I worked for the government. It felt more like a community: everyone was friendly and worked more or less toward the common good. I realized for me and my personality style that the corporate ladder I wanted to climb wouldn’t be in that environment; however, it was a great experience for me to have and learn that I wanted to work in the private sector. I chose my first two co-ops leading up to my third to help maximize the opportunity for employment after graduation. Whether you have a good experience or not, you can always take something from it.”
How did you approach your co-op search? Is there anything you would do differently if you were a student today?
“I had a very methodical approach because my whole college career was targeted towards being an actuary. At the time, it was very hard to get an actuary co-op for your first placement. The employers required you either pass an exam or have prior experience, but I didn’t have either. So, the first co-op I completed was business related so I could acquire finance experience—actuaries are math heavy, but also financial related. My second co-op was with the department of defense and seemed interesting. All three of my co-ops had components that allowed me to learn more about the workforce and about career options in general. If I were to do anything differently today, I would spend several hours reading job descriptions because even if it’s not directly related to your major, you can still learn from the experience. Don’t think that because you don’t have enough skills that you shouldn’t apply, the worst they can say is no.”
Could you explain what you currently do for a living? What is a normal day at work like?
“I was an actuary after school for a few years, but then I moved to New York City and I now work as an associate for a life insurance brokerage firm. We work with ultra-high net worth individuals and family offices with their estate planning goals. Before I was an actuary, I worked at a life insurance firm and we sold a product which was life insurance policies. Now, I work for a brokerage firm which means that we look at all the life insurance companies and all the products they have to offer, we know the client’s goals and we help find the best product for them based on their needs. We aren’t tied to one company so we can find what works best for each individual client. A normal day for me is about 30% analysis. I use my knowledge of math and insurance to look at a client’s life insurance portfolio (or lack thereof) and try to find a policy that could be good for them. The next 30% of my role involves answering client phone calls, answering questions, and attending meetings. Finally, the last 40% of my responsibilities involves project management – making sure that when we are in meetings, all action items are accounted for, making sure we are meeting time lines, helping different department scollaborate and ensuring things are progressing smoothly. My job is super dynamic which is why I love it; it’s very different day in and day out. All my jobs and co-ops—even my lifeguard position in high school—helped me reach this point in my career because I learned different skills to apply later. For example, if I have a difficult client, I understand how to approach them because it is similar to having an angry parent at the pool whose child is in “time out”. You continue learning things from each experience, even if it does not seem directly related.”
What is your key piece of advice for anyone attending Northeastern?
“Take advantage of all of the co-ops because that is why you’re at Northeastern and make sure to learn something at every co-op. Build your network, find mentors, and be flexible. Northeastern is building a great list of alumni in many different cities and the more connections you make in school will make the world feel smaller.”
Co-op and COVID: Working at Indigo Agriculture
Mira Rauch is a fourth-year undergraduate student studying Environmental Science with a concentration in conservation science and a minor in East Asian Studies. In Spring of 2020, she began a co-op at Indigo Agriculture. We reached out to hear about her experience.
Could you tell us about your co-op journey?
“I’m currently on my third co-op, but during my second co-op, the pandemic hit and it changed the course of that co-op when everything seemed to turn upside down. I started at the university as a Biology major and that was fun, but during my second year, I realized that was not what I was interested in pursuing. Following my first co-op in quality control at Alnylum Pharmaceuticals, I switched my major to Environmental Science and found my next co-op at Indigo Agriculture in Charlestown as a field scientist. I did a little bit of lab work but most of my co-op was on the computer doing biostatistics in analysis and some management. I worked with seeds that were coated in a special substance containing microbes—I always called it “yogurt for plants”. We would coat seeds in microbes that we knew they liked in order to be able to grow 10% more cotton or corn or 20% more wheat in places that were colder or had a dryer season than usual. My job was to manage the scientific trials to figure out where different microbes worked the best and on which crops they had the best results. I also ran the soil sampling program and did lab work during the pandemic. My current job is at MIT Energy Initiative where I am the graduate education assistant helping to write content for the energy-based master’s program. I’ve always sought to try different things with my co-ops and I think that has worked out for me.”
What did a regular day of work at Indigo Agriculture look like for you before COVID-19?
“There were about 10 people on my field sciences team and I was the team’s first co-op. I began work each day at 9 am and really enjoyed the interconnected workplace culture. I was at the end of the pipeline where I tested the microbes in real world settings.. My manager and I would check in twice a week for about an hour and he would assign me projects, most were long term and lasted from a week to a month. Most of our work since I began in January was looking at the previous seasons to analyze and make decisions about planting for the coming season since they would have to start planting again in March. We had 25-30 co-ops across the teams which was great. We would all have lunch together, hang out, get coffee together. We also had all hands meetings where the entire company would get together and leadership would field questions from all of us. I learned that when working in a biotech company, you are the pioneer of your product and the pioneer of what you’re working with.”
What did a regular day of work look like for you after COVID-19?
“In March we were getting ready to start shipping out for the spring planting season which is arguably the most important time for an agriculture company. We had to make sure everything was running like a well-oiled machine. We got an email from the CEO saying we had to work from home tomorrow. We thought it was going to be a week, maybe two weeks, and then everything would be back to normal. I grabbed just two things from my workspace and never went back. Fortunately, our team was familiar with zoom because we already had remote employees. My manager and I didn’t have a check in call for about a month because things were so turned around. To keep our spirits up, and remain connected, we did fun weekly questions on our Slack channel where we would ask and answer random questions like ‘what does your desk look like?’
How did COVID-19 impact your work?
“I ran our soil sampling project from my home which meant I got FedEx shipments of envelopes and had to hand write two hundred labels onto bags with QR codes that were registered to my house. Indigo extended my co-op through August and I was assigned a project where I took the wheat that we harvested from the past season and I placed it into a little instrument that would tell me how many carbs, oil, and protein it contained. In July I went back to the Indigo lab which was felt bizarre. We had to wear masks all day, complete a Wellness Check similar to the one Northeastern uses, and all snacks were made to be individually packaged. Only science teams were allowed to return, so we would each have our own lab bench and no more than two or three people in the same room.”
What were your work expectations and how did that change over time?
“One of the work expectations I had when I started was traveling for work. That clearly did not happen and was cancelled early on. It was heartbreaking because I was really looking forward to some sort of travel element in my second co-op. Instead, we did a lot of zoom calls to try and keep business moving forward from afar. I also expected to be able to spend more time with the other co-ops but once we went remote, it was really hard to stay connected.”
How do you think this experience is going to help your plans for the future? What lessons did you take away from this experience?
“I learned that I value having time at home and I would really consider taking a job where there is a hybrid opportunity, even after the global pandemic is over. I like to spend time with my pets and make a warm lunch instead of having to pack a cold one. In the future if I had the space to have a home office, I would absolutely take the chance to work at home two or three times a week. Additionally, I saw the importance of team communication more now than ever before. During my first week at Indigo I had to attend a one-on-one meetings for thirty minutes where I learned what my teammate did for work, what my role would be and then share what I hoped to get out of this experience and it was so helpful. I think it was so important to have this casual conversation over coffee and I think it’s worth it to push your employer or team to facilitate connection because it is very isolating to work from home. At the end of the day, we are all people who stare at the computer all day so it’s important to emphasize our other passions and activities.”
Is there anything you learned from your last co-op that you could apply to your current co-op?
“Definitely virtual coffee, I think that’s for everyone. I know it feels awkward, but tell your manager and make one on one appointments to get to know everyone on the team. Lean into the discomfort of not having water cooler talk. Secondly, something I wish I could give to every single co-op who is nervous is confidence. When I entered my first and second co-op, I was acutely aware that I know less than every single person I work with and that’s okay, but over time at Indigo my team would ask me questions and lift me up. It was really enriching to feel like my opinions mattered even though I was a co-op. Also, if you are the new person, you should lean into being the new person. Ask plenty of questions because you’re new and you’re not expected to know everything. If you’re really embarrassed, throw in “I’m taking a class on this next semester but we haven’t gotten there yet, can you walk through this with me?” and they’re going to love it. Lastly, write down everything you do at co-op so you can add it to your resume later on. Keep a notebook so you have a list for reference in the future.”

My Co-op Experience: Wrann Lab at Massachusetts General Hospital
In January 2020, I started my first co-op as a research technician at Dr. Christiane Wrann’s laboratory at Massachusetts General Hospital. The research at the Wrann lab focuses on investigating the role of an exercise hormone, irisin, as a therapeutic for Alzheimer’s disease using mice models. We also study how the deletion of irisin’s gene impact the progression of Alzheimer’s.
I was involved in understanding the genotype characteristics of transgenic mice undergoing different behavioral or viral injection treatments. I have contributed to the project by performing experiments, presenting results, discussing the necessary next steps for the research, keeping track of inventory and editing grants/papers. I was also in charge of reviewing journal’s guidelines to format our paper accordingly.
Mid-March, Northeastern closed campus due to the pandemic and I returned home to Florida. During this stressful situation, Dr. Wrann and MGH allowed me to stay in the system. Although the work became remote, this led me to learn more computational aspects of research such as image and statistical data analysis. Specifically, I learned the software GraphPad Prism in great depth so that I was given charge of preparing data analysis and 100+ figures for a research paper that is currently under revision. In June, once laboratories increased capacity, I returned to Boston and extended my co-op until Fall classes started.
The team of research technicians and post-doctorate fellows at the Wrann lab were extremely enthusiastic about teaching and guiding me in my scientific journey. They were always happy to explain the science behind techniques and the reasoning of the research. Therefore, my experience surpassed my expectations of being exposed to wet lab techniques. I felt that I was contributing to the basic scientific process of the research.
This experience was an excellent introduction to translational research methods for neurological problems, preparing me for my future goal of entering an MD/PhD program. The co-op program only affirmed that I enjoy being part of the academic process of medicine. I have started my second co-op at Northeastern’s Action Lab under the Schafer Research Scholarship and I am excited for another exceptional learning experience for the next 6 months.
Don’t worry about the koi fish on campus this winter–they’re just chilling
Tucked into the heart of Northeastern’s Boston campus is a tiny oasis from the hustle and bustle of city life. A koi pond, located between the Curry Student Center and Robinson Hall, sparkles in the sun and gurgles as a small waterfall splashes into it. Vibrant, nearly fluorescent koi flash just under the surface.
But what happens to these fish—a dozen or so live in the pond—during the winter?
“They chill out,” says William Detrich, professor of marine and environmental sciences at Northeastern. He means it literally.

The Ribosome: Is it the Key to the Next Generation of Antibiotic Therapies?
Imagine a novel antibiotic treatment that instantly kills bacteria and poses zero risks to humans. This therapy may be closer to reality than we once thought possible, thanks to the Whitford Research Group. Their recent publication in the esteemed journal Nature Communications highlights opportunities for the next generation of antibiotics through the study of the ribosome. The ribosome is a biomolecular machine responsible for producing the proteins that make up all living organisms. Every cell requires ribosomes to survive, including pathogens, like bacteria, that can be harmful to human health. Shutting down a ribosome means rendering a cell unable to survive – while bad news for destructive bacteria remains good news for scientists. A team at Northeastern University may have found a way to harness the functionality of the ribosome, elucidating a tremendous opportunity for the development of novel broad-spectrum antibiotics.
The team’s most recent published research, “A steric gate controls P/E hybrid-state formation of tRNA on the ribosome” was performed at the Massachusetts Green High Performance Computing Center (MHPCC). Funded by the National Science Foundation since 2014, Dr. Mariana Levi, Kelsey Walak, and Dr. Paul Whitford of Northeastern performed hundreds of simulations on structural elements of the ribosome using high performance computers. Their research focuses both on understanding the structure and function of the ribosome as well as finding key features that control its motion, with the ultimate goal of using them as experimental targets for potential antibiotics. “This is the first study where we actually have a strong signature of an antibiotic target,” said Dr. Whitford.
Harnessing the power of high-performance computing, a tool used for intensive computational tasks, the team developed a model that has identified a region on the ribosome unique to bacteria but absent from humans. Targeting this region pharmaceutically could kill bacterial cells without harming human ones. This finding is historic: “[Most previous studies] didn’t know where to look…it might take a thousand graduate student years to try out all of the possible regions that could be important…We’ve reduced this by maybe 95 percent,” says Dr Whitford. Working with the Research Computing Group at Northeastern, they went through hundreds of simulations to narrow down this target region using an in-house model developed by Dr. Levi. She credits the success of this model to the resources available to researchers for free at the MHPCC: “Our lab is our computer, so we really have to have a deeper understanding of what’s going on.”
This study is just the foundation for what is yet to come from this group. “We have something to say and add to the discussion,” says Dr. Levi. Their contributions extend not only to the community of ribosomal study but to those looking to leverage these innovative solutions to treat bacterial disease. “It’s much more than just computational simulation,” Dr. Levi adds, “This is just the beginning.”
