Weinstein group, University of Sheffield


Quantum control of electron transfer in molecules ; ultrafast 2D infrared spectroscopy; artificial photosynthesis.

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.

Graduate Students


2019 - present

BSc Chemistry, 2015-2019

National Taiwan University

Born and raised in Taipei, Taiwan, Cheng is still adapting to the weather in NYC. In his undergraduate years, he obtained research experience in Professor Chun-hsien Chen’s group working on molecular electronics using mainly customized scanning tunneling microscopy, where he developed a strong interest in studying electron transport behavior in materials. He is looking forward to gaining insight on controlling electron flow in the Delor group. When not in the lab, he may be delocalized in NYC trying something new.


2019 - present

BA Chemistry and Global Health, 2015-2019

Washington University in St. Louis

Vicky grew up in Shenzhen, China with interests in music, oil-painting and fencing. She received her B.A. in Chemistry and Global Health from Washington University in St. Louis. Previously, she worked in Professor Sophia Hayes’ lab on solid-state NMR crystallography of CO2 mineralization products. In the Delor group, she works on ultrafast microscopy of semiconductor heterostructures and plasmonic superlattices.

2019 - present

BSc Chemistry, 2014-2019

Wuhan University

​Visiting researcher, North Carolina State University

Ding is from Zhejiang, a coastal province in eastern China. Raised in a handicraftsman family, he is good at woodwork, weaving, painting, and cooking. During senior high school, he became interested in chemistry, which answered his questions about the mechanics of daily phenomena, such as rice-made paste, swelling of fishnets, fermentation and so on. In college, he began to study the doping of two-dimensional materials (Fu group). He successfully synthesized a series of lanthanide-doped TMDs and studied how lanthanide modifies the optoelectronic and catalytic properties of TMDs. In 2018, he worked in the Dickey group as a visiting student, where he developed a method to prepare ultrathin metal oxide films at ambient environment. He is now a graduate student in the Chemistry Department of Columbia University.


2020 - present

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.

2020 - present

BS Chemistry, 2016-2020

University of Texas at Austin

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!

Undergraduate Students


2016 - present

BA Chemistry and Mathematics

Columbia University

Eileen is from Potomac, Maryland, and is an undergrad in Columbia College earning a B.A. in chemistry and mathematics. Her interest in chemistry started with an early high school introduction to organic chemistry, and in college shifted to mathematics as well, in terms of physical and quantum chemistry. In the Delor group, she is interested in the propagation and imaging of plasmon-polaritons in 2D metal halide perovskite materials. On campus, she is involved in UN Ivy STEM Connect, a volunteer initiative to remotely tutor students in Cameroon and Senegal in STEM subjects, she is a member of Kappa Alpha Theta, and she spends much of her free time walking her dog.


Summer 2020

BS Chemistry & Neuroscience Co-major (2017 - present)

Miami University of Ohio

William grew up near Cleveland, OH and is entering his senior year at Miami University of Ohio, earning a B.S. in chemistry with a co-major in neuroscience. At Miami, he has worked on research projects related to organic methodology development, mechanistic studies, and electrocatalysis (Liu Group). William acquired an interest in materials science when he went on to research the self-assembly of various oligomers (Hartley Group). He is excited to have the opportunity to engage in materials research in the Delor group through the 2020 Columbia University MRSEC Summer REU program. In the Delor group, he is working on simulating the rotation of excitons in '2D' material with python programming. Aside from researching in the lab, William loves being outdoors; hiking, skiing, and cliff-jumping are some of his favorite activities.
