What happens to a device once it leaves the cleanroom and has to work in a system, and how to most efficiently use the energy it generates.

Getting every watt off the array

I work on the Array and Battery teams of Stanford Solar Car, where our goal is to extract as much power from the sun as possible, taking into account factors such as heat, electrical integration, and the fact that it's on a car zooming across a continent.

  • Characterize Maxeon Gen III cells by outdoor four-wire IV sweep on a Keithley 2461, and analyze 3×6 modules for mismatch loss to inform cell binning and array layout.
  • Lead infrared and electroluminescence inspection to find hotspots, cracks and interconnect faults; piloted a new encapsulation method for durability and water-ingress resistance.
  • Build Python tools modelling bypass-diode configurations and temperature-driven efficiency loss, to inform thermal and cooling design for the next-generation array.

Saving energy in Stanford's residential buildings

  • Audited 320 common spaces across 45 buildings and roughly 2,900 lighting elements to map occupancy-sensor coverage, found only 36.9% of spaces had them.
  • Built an ROI model from the audit data projecting 66,421 kWh and $11,941 in annual savings against $65,650 upfront, a payback of about 5.5 years.
  • Evaluated vendors and specified hardware for a window-sensor HVAC pilot.

Organic transistors and OLEDs

  • Fabricated bottom-gate PDBT-co-TT organic thin-film transistors (OTFTs) with a PFBT self-assembled monolayer on the gold contacts, confirmed by goniometry (36.7° to 64.3° contact angle). Extracted threshold voltage and saturation mobility from transfer curves and measured 13% higher mobility, consistent with reduced interfacial trap density.
  • Built F8BT OLEDs with PEDOT:PSS and PFN-Br injection layers and a 100 nm aluminum cathode evaporated at SNF. Used matched electroluminescence and photoluminescence peaks to attribute an anomalously high turn-on voltage to spin-coating defects rather than interlayer energetics.

Previously

Wetland Ecosystems Group Stanford Jun 2025 – Jun 2026

Examining drought impacts on wetlands in Louisiana, Maryland and Florida

  • Tracked wetland change across all three states by remote sensing, with geospatial analysis in Google Earth Engine, ArcGIS and R.
  • Supported fieldwork in Louisiana.
  • Processed 150+ samples back on campus by cryomilling, acid digestion, CHN elemental analysis and ICP-OES to get their C:N:P ratios.
  • Wrote the sample-prep SOP for cryomilling and digestion.
  • Second author on an AGU abstract.

This was my first research position at Stanford, where I first got hands-on lab and data analysis experience.
