Educational Experience

2019 – Present
Principal Scientist —
2017 – 2019
Science Quiz Writer
I write science, engineering, and computer science content for, which provides online STEM education. I’ve worked on courses and challenges covering a wide range of topics including solar energy, scientific thinking, and cryptocurrency. I design my lessons to be broadly accessible without sacrificing technical accuracy.
2018 – Present
Tutor — Signet Education
I work as a subject tutor for Signet Education, covering a variety of technical subjects including math, chemistry, physics, and engineering. While the primary goal of subject tutoring is to improve a student's understanding and grades in the relevant course, I also strive to instill a passion for learning and an appreciation of science and math in my students.
2018 – 2019
Production Lead — Principles of Munfacturing MicroMasters
I helped facilitate and develop the Manufacturing Process Control and Management in Engineering courses for the Principles of Manufacturing MicroMasters program.
2014 – 2017
Mentor — MITxplore
As a mentor for MITxplore ( I worked with about ten 4th – 6th grade students per semester during weekly math outreach sessions. I also developed lessons to make complex math topics accessible and engaging for young students.
Spring 2016
Teaching Assistant — 2.55: Advanced Heat and Mass Transfer
I was a teaching assistant for course 2.55 (graduate level heat transfer) at MIT. I organized and led recitation sessions, office hours and exam review. I earned an overall rating of 6.8/7 on my course evaluations in this position.

Research Experience

2015 – 2018
Solar-Thermal Aerogel Receiver — MIT
I was part of a team that developed a novel solar-thermal aerogel receiver, which achieves efficient solar to thermal conversion using transparent silica aerogel. I modeled system performance as well as fabricated and characterized experimental prototypes of the receiver.
2016 – 2018
Determining Performance Limit of Spectral Selectivity — MIT
I worked on determining the limit of performance enhancement possible using spectral selectivity (e.g., in solar thermal systems) for physically realizable surfaces. In this work, limits were set by the Kramers-Kronig relations in conjunction with selected physical constraints.
2014 – 2018
Hybrid PV-Thermal Solar Receiver — MIT
I helped design a spectrum-splitting hybrid PV and thermal solar receiver, and developed an integrated model spanning the receiver sub-components to predict overall system performance.
2012 – 2015
Macroscale Optical Cavity for Solar Receivers — MIT
I designed an optical cavity to reduce radiative losses from solar receivers. As part of this project, I programmed a ray tracing code to predict cavity performance and experimentally demonstrated reduced thermal losses from a receiver at elevated temperature. I also used ray tracing to show an improvement in absorption of photovoltaic cells with the cavity.
2011 – 2015
Solar Thermoelectric Generator (STEG) — MIT
I helped design an improved efficiency STEG using optical concentration and modeled the device efficiency using heat transfer analysis. I tested a prototype STEG with integrated thermal storage.
2010 – 2011
Energy scavenger from fluid flow — UC Berkeley
I helped develop a piezoelectric energy scavenger for use in HVAC ducts. My work on the project improved power output from 3 µW to 2 mW, or approximately 700x increased performance. I modeled the fluid dynamics and solid mechanics of the system to optimize design, prototyped a variety of designs and completed performance and fatigue testing on prototypes.
