Research Directions

My research experience has focused on improving the conceptual understanding of multi-loop integrands, and more generally developing computational methods for wrangling perturbation theory using gauge-invariant building blocks.

Recently, I have been leveraging my multi-loop background to explore novel methods for studying gravitational radiation effects in binary black hole systems.

Some of my guiding questions:

• Are any point-like theories of gravity “safe”?
• Is there a universal explanation for when color-kinematics duality – a surprising relation between gauge theories and gravity – succeeds or fails?
• Can we exploit color-kinematics duality to unlock simplicity in gravitational wave physics? What about cosmology?
• What physical insights are hiding just beyond the next computational wall?

About me

Hi, I’m Alex, a research associate in the Amplitudes and Insights group at Northwestern University. I earned my PhD in 2019 from UCLA, and spent 3 years in Uppsala, Sweden as a postdoctoral researcher. I study theoretical physics by day, and play board games by night.
