Milan was born in Nice, France, but grew up on Reunion island in the Indian Ocean, where his primary concerns were scuba-diving, bodyboarding, sailing and trekking. He completed his higher education in the UK, where after a masters in theoretical astrophysics he switched to experimental physical chemistry to study artificial photosynthetic systems using ultrafast infrared spectroscopy. In his PhD, performing experiments in Sheffield and at the Central Laser Facility (Rutherford Appleton Labs), he developed a new approach for predictive quantum control of intramolecular electron transfer in the condensed phase using vibrational excitation. In his postdoctoral years at UC Berkeley, he developed a generalizable interferometric ultrafast microscope capable of tracking energy carriers diffusing through any semiconductor in 3D with few-nm precision and picosecond resolution. He was appointed as Assistant Professor at Columbia University in 2019.

BS Chemistry, BS Physics, 2016-2020
University of California, Los Angeles
Born in Tashkent, Uzbekistan, Jack spent most of his formative years across the United States, from Orlando, to Philadelphia, to glamorous Fresno. While he always enjoyed science, it wasn’t until freshman year at UCLA where he developed a serious interest (unhealthy obsession) in quantum mechanics and materials science when he discovered that it explained how day-to-day electronics functioned. His curiosity led to research in Sarah Tolbert’s lab, where he synthesized multiferroic nanocrystals for applications in memory devices. His interest in being able to "see" the submicron world led to work in the structural characterization of semiconducting polymers and, eventually, research in Naomi Ginsberg’s UC Berkeley lab on the self-assembly of rubrene spherulites. Jack is excited to return to the East Coast and is looking forward to finding a reliable food truck to fuel his neverending desire for cheap comfort food.
