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.

Universidad de Costa Rica
​
Victoria, originally from Costa Rica, developed a strong interest in materials research during her undergraduate studies. She joined the Materials Science and Engineering Research Center (CICIMA) at Universidad de Costa Rica and spent a summer at Whitesides Research Group at Harvard University. These experiences inspired her to explore emerging materials for optics and photonics, leading her to pursue a Ph.D. at Georgia Tech under the guidance of Prof. Natalie Stingelin and Prof. Carlos Silva. During her doctoral research, she developed fully solution-processed optical microcavities for polariton-based technologies and characterized organic and two-dimensional metal-halide exciton-polaritons in the time domain. Currently, as a Columbia Quantum Initiative Postdoctoral Fellow in the Delor and Schuck Labs, Victoria investigates semiconductors with quantum-confined excitons for nonlinear optics, with emphasis on exploiting their cooperativity and transport properties.

Fuyang grew up in Johor Bahru, the southernmost city in Malaysia. He earned his B.S. degree in Physics from Nanyang Technological University (NTU), Singapore, in 2018. After graduation, he worked as a project officer at NTU for a year under the guidance of Prof. Baile Zhang, contributing to various projects on free electron radiation and fluid flow invisibility cloaks. During his PhD, Fuyang focused on terahertz time-domain magnetospectroscopy to investigate magnetic properties in quantum materials at extreme conditions and cavity quantum electrodynamics phenomena in solid-state systems. In 2024, he moved to New York as a postdoctoral researcher in the Delor and Basov groups, where he studies polaritons in van der Waals materials through far-field and near-field microscopy. Outside the lab, Fuyang enjoys exploring New York City, particularly its museums and restaurants. Having grown up in a tropical country, he treats adapting to New York’s freezing winter as one of his latest research interests.

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.

Inki was born in South Korea and hails from Denton, Texas. He became interested in chemistry when he was in high school, and in college he began to enjoy studying physics and math. At UT Austin, he worked with Dr. Sean Roberts to investigate energy transfer from lead sulfide quantum dots to organic molecules using ultrafast spectroscopy. Although a large portion of his research consisted of synthesis and characterization, he particularly enjoyed studying light-matter interactions. Inki likes to watch Netflix in his free time, and he is excited to move to the Big Apple!

University of Maryland, College Park
Andrea has had an affinity for science and art since childhood. She attended the University of Maryland, College Park as a chemistry major. It was there she began her research experience in Dr. John Fourkas’ group, studying the interfacial organization of liquids using vibrational sum frequency generation spectroscopy under the mentorship of Dr. Amanda Souna. Along with her burgeoning interest in research, Andrea’s passion for teaching led her to become a middle school science teacher for three years, a position which she loved and where she established lasting friendships. She is excited for her time in graduate school at Columbia, and is grateful for the people who have and continue to believe in her. Outside of work, she enjoys outdoor strolls in the park, quality time with friends and family, cooking, knitting, and bookmarking places to eat on Google Maps.

Stuck in the suburbs of Pelham, Alabama, Michelle grew up dancing ballet, attending night sessions at a local photography school, and painting stills to pass the time. Moving to NYC on a whim, she received her A.A. at Bard High School in Manhattan and later, her B.A. in Chemistry near the snowy Catskills of upstate New York at Bard College, where she worked in the Anderson lab to characterize the luminescence of Pt/Ni based complexes. In the Delor group, she uses ultrafast microscopy to study energy transport in semiconducting materials.

BS Chemical Engineering, 2018-2022
University of California, Berkeley
From San Diego originally, Noah stuck around California to complete his B.S. in chemical engineering, with a minor in city and regional planning, at UC Berkeley. During his undergraduate years, he worked at Lawerence Berkeley National Laboratory with Dr. Jason Cooper on the synthesis and spectroscopic characterization of CO2 reduction reaction photocatalysts. After then spending a year at École polytechnique fédérale de Lausanne under the supervision of Professor Raffaella Buonsanti to continue research on CO2RR, there in the context of colloidally-synthesized nanocrystal electrocatalysts, Noah is now excited to investigate light-matter interactions and electron transport at a more fundamental level. When not in the lab, Noah enjoys playing soccer, science journalism, and exploring New York City, if not struggling with the lack of sunny weather.

Brigham Young University
Raised in the shadow of the Las Vegas Strip, Simon grew up hiking and participating on his school’s quiz bowl team. Following high school, he took two years off to serve as a volunteer in Greece and Cyprus (don’t ask his opinion on Greek food if you’re in a hurry!). He then attended Brigham Young University in Provo, Utah, where he researched collisional energy transfer under the direction of Dr. Eric Sevy, a fellow Columbia alum. He graduated with a B.S. in Chemistry and a minor in physics. He is excited to transition from gas-phase to solid-state research in the Delor lab. When not in the lab, he enjoys watching football, playing the piano, and being in nature, though the lack of mountains nearby does still somewhat perturb him.
