Bio-Integrated Electronics and Systems Lab (Prof. Jaewoong Jeong, KAIST EE) 

• Developing a wireless, flexible neural interface that combines μLED-based optical stimulation with transparent microelectrodes for simultaneous electrophysiological recording at the same site

• Currently at the system integration step, including Bluetooth module programming for wireless control and data transmission, artifact suppression

• I found nRF programming challenging at first due to the limited technical documentation,
  so I put together these notes — hopefully they'll be helpful for other beginners! 

Co-work with Prof. Zhenan Bao's Group (Stanford)

• Designing and testing circuitry for ingestible device supporting gastrointestinal tract serotonin sensing, pressure sensing, and electrical stimulation

• Focusing on power management and compact PCB layout for stable operation in an ingestible form factor, harsh gut environment

Work done as summer intern at Prof. SeokHyun Andy Yun's lab (MGH, Harvard Medical School)

• Researched biolaser particles for cell labeling and tracking — a paradigm shift from conventional fluorescence-based methods

• Built an automated fabrication pipeline using femtosecond laser photochemical etching and motor-stage control software

• Optimized laser particle etching conditions

• Won the People's Choice Award at the final poster session
