Hi, I'm Mark!
I'm a postdoc at Amherst College working with Professor Daniella Bardalez Gagliuffi! I earned my PhD at the University of Pennsylvania in May of 2024 where I was a National Science Foundation Graduate Research Fellow.
When I'm not running code, digging through data, or looking for planets, I enjoy making pizzas, trying to play the guitar, and visiting different baseball parks (go Phillies!).
