Postdoctoral Associates

M. Junaid Amin
(joint with Prof. Petry and Prof. Shaevitz)

Ph.D. 2016, Electrical Engineering, University College Cork, Ireland

Email: mja5 (at)

Junaid completed his undergrad from Lahore University of Management Sciences (Pakistan) in Electrical Engineering in 2012. He obtained his PhD in Electrical Engineering from University College Cork (Ireland) in 2017 where he worked on optical imaging and sensing systems. Here at Princeton, he is developing new microscopy platforms to investigate dynamic microscopic systems for biological, physical chemistry and material applications. Outside the lab, he enjoys playing cricket and table tennis, and closely follows his favorite English Premier League side Arsenal through thick and thin.

Joseph S. Beckwith

Ph.D. 2019, Physical Chemistry, University of Geneva, Switzerland

Email: joseph.beckwith (at)

Joe obtained his PhD from the University of Geneva in 2019 working on ultrafast spectroscopy. He then decided to switch to more complex systems, moving to Princeton to do that as an SNF early postdoctoral fellow. His project involves building a new multi-resolution 3D microscope to understand chemical reactivity inside cells. Outside of the lab he enjoys cooking, comedy and running, not necessarily in that order.

Nyssa T. Emerson

Ph.D. 2019, Chemistry, Princeton University

Email: ntemerso (at)

Nyssa remains mysterious.







Ju-Young Kim
(joint with Prof. Ryota Iino of the Institute of Molecular Science, Japan)

Ph.D. 2019, Department of Chemistry and Biochemistry, University of Notre Dame

Email: juyk (at); (at)

After Ju-Young earned her Ph.D. degree from University of Notre Dame majoring Surface-Enhanced Raman Spectroscopy, she worked as a postdoctoral fellow at Northwestern University with Prof. Van Duyne (1945–2019) for a year. She then moved to Princeton to study single-molecule imaging based on Foster resonance energy transfer as an NINS postdoctoral fellow (National Institute of Natural Sciences, Japan). Having had brutal Midwestern winter for years, she is now ready to enjoy the relatively warmer east side!

Tian Zhao

Ph.D. 2019, Chemistry, Pennsylvania State University

Email: tianz (at)

Tian obtained his Ph. D. in physical chemistry from Pennsylvania State University in 2019. Tian is currently developing a new generation of 3D multi-resolution system aiming to understand physical and chemical behaviors of the single unit in complex systems.

Graduate Students

Hugh Wilson
(joint with Dr. Quan Wang, a Lewis-Sigler Fellow)

B.A. M.Sci. Natural Sciences (Physics), University of Cambridge

Email: hswilson (at)

Hometown: Yorkshire, United Kingdom

Hugh grew up in Yorkshire in the United Kingdom. He completed his undergraduate studies at the University of Cambridge in Natural Sciences, specialising in biological and condensed matter physics. During his final year he worked in the lab of Dr. Ulrich Keyser on the diffusive motion of colloids in microfluidic channels. He then joined the Princeton community as a graduate student in the Quantitative and Computational Biology programme and is currently a joint student with Quan Wang. In his spare time Hugh likes running and travels occasionally.


Fernando del Castillo

Class of 2023, Princeton Universiy

Email: fadc (at)

Hometown: Planet Earth

Fernando is a Junior undergraduate at Princeton University, currently on a leave of absence, and will be majoring in Chemistry with certificates in Biophysics and Materials Science. He hopes to continue on to study a Ph.D. in Chemistry after graduation. Fernando is currently working with Nyssa Emerson as his mentor in computationally modeling the Fluorescence Enhancement around metallic nanoparticles and optical antennas. Outside of studying and doing (remote) lab work, Fernando enjoys playing soccer and tennis.
