I'm Sorry, But You Will Have To Do Math In The Future Mirrors in space are a dumb idea.

This is a paper explainer for my recent work with my graduate student Eric Putney, previous Rutgers postdoc (now at Institute of Basic Science in Korea), and my Rutgers colleague David Shih.

Given that it is 2025, the dumbest thing I’ve seen this week is some stiff competition, but “AI datacenters in space” is some impressive idiocy.

This is a paper explainer for my recent paper “General Constraints on Isocurvature from the CMB and Ly-$\alpha$ Forest” by myself, Peizhi Du (Rutgers postdoc until recently, now a newly-minted faculty member in China), Nicolas Fernandez (Rutgers postdoc),…

Today, along with about 230 other academics from New Jersey universities, both public and private, I sent a letter to the Senators of New Jersey (Andy Kim and Cory Booker) about the threats to scientific research and higher education that are occurring wi…

This is work that I did with my student, Eric Putney, then-Rutgers-postdoc Sung Hak Lim (now at the Institute for Basic Science in Daejeon), and my colleague David Shih.

This is a paper I wrote with Tracy Slatyer at MIT, her student Yitian Sun (now a postdoc in McGill), Sidd Mishra-Sharma (previously a postdoc at IAIFI, newly hired as a professor at Boston University), and my student Ed Ramirez.

This is a paper explainer for my recent paper “Force-feeding Supermassive Black Holes with Dissipative Dark Matter” with Rutgers postdoc Nicolas Fernandez.

I want to tell you about my most recent paper “Dark Radiation Isocurvature from Cosmological Phase Transitions,” which I wrote with my coauthors Mitch Weikert, Peizhi Du, and Nicolas Fernandez.

This is an explainer for my most recent paper, with my Rutgers colleague David Shih, Lina Necib at Caltech, and UCSC grad student (and a Rutgers undergrad alum) John Tamanas.

The cosmic web of galaxies as seen by SDSS.

Cartoon of the structure of dark matter objects.

I just got back from a two week workshop on dark matter hosted by the Aspen Physics Center.

This is an explainer for my recent paper with Gopolang (Gopi) Mohlabeng and Chris Murphy on the implications of recent surveys of dark matter velocity distributions from the Gaia mission on dark matter direct detection.

Asymmetry Observables and the Origin of $R_{D^{(∗)}}$ Anomalies This is an explainer of my recent paper, written with my colleague here at Rutgers David Shih, and David’s graduate student, Pouya Asadi.

I'm visiting the University of Oregon's theoretical physics group, and gave a talk on some of my recent work on extracting dark matter particle physics from astrophysical measurements.

This is description of my recent paper with Annika Peter of OSU, where we consider how to use gravitational measurements of dark matter (that is: astronomy and cosmology) to understand the particle physics of dark matter.

My colleague from OSU, Annika Peter, and I just put out a fairly massive paper, thinking about all the ways we can learn about the particle physics of dark matter by looking at its gravitational effects on astrophysical systems.

A few months ago, I wrote a paper with some of my fellow physicists at Rutgers: a graduate student Pouya Asadi, postdocs Anthony DiFranzo and Angelo Monteux (now a postdoc at UC Irvine), and fellow professor David Shih.

Last night, I gave a talk to the Rutgers Society of Physics Students, the STAR group, and the Astronomical Society on dark matter: the evidence for it, how we look for it, and some thoughts about how will we be looking for it in the future.
