Deshan Perera
Postdoctoral Scholar, Biology
BioI am a Stanford Data Science Postdoctoral Scholar in the Department of Biology at Stanford University, supervised by Prof. Hunter Fraser. My research focuses on evolutionary dynamics and the development of high-performance computational tools to analyze complex biological systems. I earned my Ph.D. in Bioinformatics from the University of Calgary, Canada, where I investigated within-host evolution in pathogen genomics and cancer. Originally from Sri Lanka, I hold a First Class B.Sc. (Hons) in Biology from the University of Sri Jayewardenepura. I am passionate about advancing computational biology through the design and implementation of scalable software solutions that leverage GPU, CPU, and SSD architectures for large-scale genomic and evolutionary analysis.

Vahe Petrosian
Professor of Physics and of Applied Physics
BioHow do things evolve in the universe? How are particles accelerated in the universe?
Professor Petrosian’s research covers many topics in the broad area of theoretical astrophysics and cosmology, with a strong focus on high-energy astrophysical processes.
Cosmological studies deal with global properties of the universe, where the main focus is the understanding of the evolution of the universe at high redshifts, through studies of the evolutions of population of sources such as galaxies and quasars or active galactic nuclei, gamma-ray bursts, using new statistical techniques developed in collaboration with Prof. B. Efron of the Department of Statistics. Another area of research is the use of gravitational lensing in measuring mass in the universe.
High-energy astrophysics research involves interpretation of non-thermal astronomical sources where particles are accelerated to very high energies and emit various kinds of radiation. These processes occur on many scales and in all sorts of objects: in the magnetosphere of planets, in the interplanetary space, during solar and stellar flares, in the accretion disks and jets around stellar-size and super-massive black holes, at centers of galaxies, in gamma-ray bursts, in supernovae, and in the intra-cluster medium of clusters of galaxies. Plasma physics processes common in all these sources for acceleration of particles and their radiative signature is the main focus of the research here. -

Oliver Philcox
Assistant Professor of Physics
BioJunior Fellow, Simons Society of Fellows (2022 - 2025)
Ph.D., Princeton University (2022)
M.A. (Cantab.), Cambridge University (2018)
I’m broadly interested in theoretical, statistical, and observational cosmology, particularly as applied to galaxy surveys and the Cosmic Microwave Background. Recently, I have worked on measuring, modeling, and interpreting new and old physics in a range of cosmological datasets, and using them to learn about the early Universe, including inflation. With Mikhail Ivanov and Marko Simonovic, I won the 2024 New Horizons Prize in Physics, for work on the Effective Field Theory of Large Scale Structure.
I am an assistant professor in the Physics department, affiliated with both the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC) and the Leinweber Institute for Theoretical Physics at Stanford (LITP). Please send me an email if you're interested in working with me!
