I am interested in developing new spectroscopic techniques to study new emerging optoelectronic materials, particularly in the shortwave infrared (SWIR). Leveraging my graduate experience on defects in 2D materials, I focus on defects that emit in the SWIR as they can dominate energy losses in semiconductors but are not well understood. By using the decay associated Fourier spectroscopy (DAFS) we are developing, in conjunction with the superconducting nanowire single photon detectors (SNSPDs) with an ultra-stable custom-built microscope I hope to image and understand defects in materials like, monolayer black phosphorous, MoTe2 and lead halide perovskites. My wife and I like to cook new food, try out new exotic LA restaurants, visit museums, generally exploring LA and to go hiking. Also, I love to play board games: Dominion is one my favorites.

My research encompasses the areas of physical and materials chemistry and steady-state and time-resolved spectroscopies. I work with organic cyanine dyes where I make self-assembled aggregates from the dyes, then perform extensive spectroscopies and cryo-electron microscopy (cryoEM) on the aggregates. The goal is to understand exciton transport in the aggregates using decay-associated Fourier spectroscopy (DAFS) and correlate it to the aggregate structure and morphology obtained from cryoEM. We want to use our knowledge of aggregation to explore novel photophysical properties, particularly, strong absorption and emission in near-infrared and short-wave infrared. I love exploring new places in LA, travelling and cooking.

I aim to develop a more in depth understanding of the coherent excitonic delocalization that occurs in self-assembled aggregates of cyanine dyes. Specifically, I am interested in determining how specific 2D morphologies can lead to states capable of greatly enhanced rates of energy transfer, and how these states can be used to develop novel energy transfer materials in both the visible and near-infrared regimes. Outside of research, I enjoy rock climbing, cooking and baking, and exploring new areas and activities

My research focuses on energetics of triplet excitons in oligoacenes, a class of organic semi-conductors. A day in the lab can vary from designing and building quick scan fluorimeter to making and characterizing nanocrystals. When not in the lab, I love exploring both locally and abroad, playing board games, and volunteering with OCDS, QSTEM, nanoscience outreach at UCLA.

My research aims to synthesize, handle, and characterize qubit molecular moieties that can bind to surfaces while maintaining their ideal qubit properties.

I enjoy developing new spectroscopic techniques to study and develop a better understanding of materials. I use decay associated Fourier Spectroscopy (DAFS), that utilizes interferometric methods, paired with superconducting nanowire single photon detectors (SNSPDs) to observe otherwise difficult spectral features in the materials. Alongside DAFS I will build and develop a highly stable microscope that will assist in connecting the spectral properties with localized areas of our materials. I will use this to study materials such as lead-halide perovskites which have potential applications in optoelectronics. In my free time, I enjoy goofing off around Westwood with friends, playing guitar and video games, admiring sloths, and chilling with my sweet cat Nutella.
