Physics
Everything (In Theory)
Why can’t light escape a black hole? What exactly is dark matter? Why is the gravitational force so weak? In physics, we know everything is bound by the same rules and happens for a reason. It’s the “why” of every action and reaction that keeps us curious.
The College of Science physics program equips you with what we know about our universe — theories on matter, the forces, space, and time — so you can reach into the unknown and answer the question… why?
Diversity & Inclusion
The College of Science supports a culture where each person feels they belong, regardless of race, color, religion, religious creed, genetic information, sex, gender, gender identity, sexual orientation, age, national origin, ancestry, veteran or disability status. We celebrate the diversity of our community, and we seek to expand representation to further excellence. We commit to be a College where members act with respect, trust, collaboration, and communication, and where inappropriate behavior is reported and acted on without fear of retaliation.

Faculty Research Areas
The Astrophysics and Cosmology group at Northeastern University is leading cutting-edge research into the nature of the universe, including dark energy, large-scale structure, galaxy clusters, black holes across all mass scale and neutron stars, dark matter searches, and MeV gamma-ray observations. Prof. Blazek’s group probes the cosmological model using analytic methods, simulations, and maps made with the largest galaxy surveys (DES and LSST). Prof. McCleary’s group conducts balloon- and ground-based observations of gravitational lensing by galaxy clusters to understand their dark matter and astrophysics (SuperBIT and LoVoCCS). Prof. Aramaki’s group develops and utilizes sensitive detectors in underground and outer space (balloon/satellite) for dark matter searches and astrophysical observations (SuperCDMS, GAPS, and GRAMS). Prof. Lin’s group utilizes ground- and space-based observatories to carry out multi-messenger study of high-energy transient signals such as tidal disruption of stars by supermassive black holes and gravitational wave events (Chandra, XMM-Newton, and HST).

Experimental particle physics research involves exploring unknown questions about nature on the smallest scales: What constitutes dark matter? Why is the Higgs boson so light? What produced the imbalance between matter and antimatter that we observe today? Are there extra dimensions? Are there new particles or fundamental interactions that are yet to be discovered? Our group in experimental particle physics works on the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) at CERN. We study precision measurements of Standard Model processes and search for signatures of new physics, such as leptoquarks, dark matter candidates, and exotic production and decays of Higgs bosons. In parallel we have a broad involvement in the operation of the CMS detector and development of new detector systems for the High Luminosity LHC upgrade.

Theoretical Biological Physics group members apply theoretical and computational tools of statistical and nonlinear physics to understand fundamental aspects of the behavior of living systems across molecular to organ scales in health and diseases. Ongoing studies probe the energetics and dynamics of large-scale biological assemblies, physical genetics, mechanical properties of cellular assemblies and biomaterials, cancer metastasis and immune system dynamics, cardiac nonlinear dynamics, and synaptic connectivity and brain function. Synergy between those different areas is fostered by the collaborative environment of the Center for Theoretical Biological Physics (website).

Group members apply theoretical and computational tools to study the quantum properties of condensed matter (solid state) systems. A major focus within the group is understanding novel and unusual phases of matter, as well as non-equilibrium aspects of materials. Ongoing studies explore the topology of quantum degrees of freedom (e.g., electrons, magnons, and phonons), quantum magnetism (e.g., quantum spin liquids), unconventional superconductivity (e.g., high-temperature superconductors and topological superconductivity), and other highly entangled states of matter with relevance to quantum information sciences. We work in a highly collaborative environment and often publish jointly with experimental groups. Synergy between different areas is fostered by the Quantum Materials and Sensing Institute at Northeastern University.

Members of our group apply techniques from Mathematics and AI to study particle physics, cosmology, and string theory, often with overlap between the subjects. In particle physics, research is focused on Physics beyond the standard model, including understanding the role supersymmetry and supergravity. In Cosmology, questions include understanding the physics directly following the initial singularity, known as inflation, the origin of dark energy, the main form of energy in our Universe that causes it to expand at an accelerated rate, and the nature of dark matter, which is some matter of unknown origin that plays a crucial role in the formation of galaxies. Finally, the study of string theory and its implications for particle physics and cosmology requires understanding the geometry and topology of extra dimensions and how to solve the stringent mathematical and physical consistency conditions that come with a UV complete theory of quantum gravity.
