Rupert Croft - Cosmology

1. Analyze Hubble Space Telescope images for measurement of galaxy parallax.
2. Develop an explainable AI algorithm using cosmological parameters as a test case.


Rachel Mandelbaum & Xiangchong Li - Observational cosmology

Gravitational lensing induces coherent distortions in the images of distant galaxies, resulting from the deflection of light by intervening mass, and the coherent distortion includes changes in galaxy shape ("shear") and changes in galaxy size and flux brightness ("magnification" ). This project concentrates on using galaxy image simulation and mock galaxy catalog to understand the potential systematic errors introduced by the magnification effect in shear estimation and the related cosmological analysis.

Alex Malz & Rachel Mandelbaum - Observational cosmology

We seek a student for an important project to inform strategic decisions for upcoming big-data galaxy survey missions by exploring data compression schemes for high-dimensional per-galaxy probability distributions representing the nontrivial uncertainty in their physical properties. Using the qp software library (Python), the student will expand upon the precursor experiment of Malz+ 2018, balancing the resource footprint to store these data products, the computational expense to decompress them for downstream analysis, and the preservation of the complex information encapsulated by the uncompressed probability distributions.

Kostya Malanchev & Rachel Mandelbaum - Observational astrophysics

1. Search for faint high-proper motion stars. Thanks to Gaia, we currently know of a few hundred stars moving in the sky faster than an arcsecond per year. In this project, the student will analyze the low-mass star population near the Sun and look for them using shift-and-stack technologies. Knowledge of Python is preferable, but not mandatory.

2. Search for fast transients in Zwicky Transient Facility (ZTF) high cadence data. The student will analyze a ZTF data release to find bright and fast transients in the variable sky. We could find gamma-ray burst afterglows, self-lensing events in binary systems, stellar flares, and other types of objects. Knowledge of Python is preferable, but not mandatory.

Biological Physics

Shila Banerjee

We are looking for motivated undergraduates to conduct theoretical and/or computational research in the area of biological physics. Possible projects include: modelling the growth and replication cycle of bacteria, phase transition in cells, computational modelling of cell mechanical properties. No prior knowledge of biology is necessary and the research projects can be conducted remotely. Prospective students are encouraged to browse through work done in our group.

Markus Deserno

My group is interested in theoretical and computational biophysics, with a focus on lipid membranes. Typical theory projects focus on membrane elasticity, shape/geometry, phase behavior, and the implications of lipid asymmetry across the leaflets of a bilayer. Computational projects approach the same subjects via molecular dynamics simulations of highly simplified models, or investigate how to measure a membrane’s elastic parameters by analyzing its fluctuations. For details, check out some of our recent work on our webpage If you’re interested in any of this, talk to me. As a prerequisite, you do not need a background in biology, but some familiarity with thermal/statistical physics is very useful. For computational projects, some experience with programming is needed, but you definitely don’t have to be seasoned coder.

John Nagle

Project 1 :  The focus is to help interpret data obtained by the neutron spin echo.technique that is a major effort carried out at reactors (NIST in the US and ILL in France). Code is being written with Prof. Frank Henrich (CMU and NIST) to fit experimental data to theories. We are currently working on how to create a user friendly program that would run at NIST and also on a cluster at CMU. Computational skills would be necessary to join this team.
Project 2: We have recently published a paper that presents an hypothesis regarding neural transmission at a synapse (Biophys. J. 122, 1118-1129 (2023). The proposed project would perform Monte Carlo simulations on a lattice to determine the range of physical diffusion coefficients compatible with the hypothesis. The student would write code to perform the simulations and run it for various sets of parameters. If exploratory work is promising, the program might be exported to a departmental cluster.


Fangwei Si

Our lab's drive is to discover “biological laws” that can help us understand living systems in a quantitatively precise way. Towards this goal, we develop/adapt tools, do rigorous measurements, and define new concepts. We are currently searching for simple yet fundamental rules connecting the complicated form of bacterial cells and their fitness in different environments. Please check out the lab website for more descriptions of our research. If you are curious about how living systems emerge from non-living matter and want to get your hands dirty in a wet lab, you are always welcome to contact us!

Stephanie Tristram-Nagle

The Tristram-Nagle lab uses x-ray diffuse scattering (XDS) collected at the Cornell High Energy Synchrotron Source (CHESS) or with the Xenocs Xeuss 3.0 at CMU to study the interaction between antimicrobial peptides and lipid model membranes that mimic real bacterial and eukaryotic membranes. These peptides are a promising new antibiotic to overcome the problem of bacterial resistance leading to super bugs. Physics students will learn how to collect and analyze x-ray data, make graphs and write results into papers. We also use circular dichroism to determine the secondary structure of the peptides as they interact with lipid membranes. Dr. Tristram-Nagle has openings for in-person students. WEBsite: 

Newell Washburn

My group is interested in understanding the physics of aging using both experimental and computational methods in collaboration with Prof. Fabrisia Ambrosio at the University of Pittsburgh. The current focus is on modeling transcriptomic changes in muscle stem cells to elucidate alterations in information flow through the gene network as a function of organism age. Our computational tools include machine learning, information theory, and by drawing analogies with classical and statistical mechanics. Email

Sara Majetich - Small Angle Neutron Scattering of Magnetic Nanoparticles

This computational project will compare theoretical models of magnetization patterns in magnetic nanoparticles with data from small angle neutron scattering (SANS) experiments. Just as x-ray diffraction arises from the Fourier transform of the electronic charge distribution in a crystal, neutron scattering can be used to reveal the nanoscale magnetization. Working with collaborators at NIST and Oberlin College, the Majetich group has investigated many types of magnetic nanoparticles using SANS with polarization analysis. Here neutrons are polarized “spin up” or “spin down” before scattering, and afterward they are analyzed to see if there have been spin flip events due to the magnetization in the nanoparticles. SANS with polarization analysis was used to demonstrate non-uniform magnetization within nanoparticles [1]. When a magnetic field is applied, surface spins may cant reversibly, depending on the temperature and magnitude of the field. For magnetite, Fe3O4, the form factors of a sphere plus a spherical shell were sufficient to explain the experimental results, but with manganese ferrite, MnFe2O4, the magnetization pattern is clearly more complex. The approach will be to assume a magnetization pattern for the nanoparticles, divide them into two-dimensional slices, take the Fourier transforms, and add up the scattering contributions from the different slices. There is already a lot of experimental data that will be useful for comparison and model refinement.
