🔬 Research Projects
Electrode Channel Pooling with OECT
08/2025 ~ present, National University of Singapore
- This project aims to increase the channel bandwidth of neural electrodes. We aggregate signals from multiple sites into a single channel, thereby greatly reducing wiring volume of electrodes.
- Theory indicates that directly summing voltages severely degrades SNR, whereas summing currents results in a much smaller reduction. Accordingly, we designed flexible electrodes based on organic electrochemical transistors (OECT) and developed a matching low-noise conversion PCB.
- We are now obtaining in vivo recordings in rats.
Fusion of Artificial Neurons and Optogenetic Neurons
08/2025 ~ present, National University of Singapore
- This project aims to invent artificial neurons capable of bidirectional interaction with optogenetic neurons using photodiodes and micro LEDs.
- I built a complete analog circuit. The front-end signal extraction module isolates clean, normalized spikes from noisy, amplitude-varying waveforms. The signal integration module combines signals (e.g., simple multi-channel spike summation or an STDP-based model). An output driver module modulates the current to control micro-LED brightness.
- We are open to collaboration on CMOS microcircuit fabrication.
Odor Source Localization based on Mesh Electrodes in the Olfactory Bulb
02/2025 ~ 08/2025, Tsinghua University
- This project aims to develop a bioelectronic nose. By recording olfactory signals in freely moving mice at locations with different concentrations, it enables spatial localization of odor sources.
- The project features: 1, Minimally invasive implantation of mesh electrodes and long-term stable recording of olfactory bulb neural signals. 2, Decoding of neuronal spikes to discriminate different concentrations of the same odor.
Deep Learning based Neuron Reconstruction from fMOST Images
10/2024 ~ 08/2025, Tsinghua University
- This project aims to digitally reconstruct single-neuron skeletons from 3D mouse whole-brain slice images acquired by fMOST.
- The task is challenging for two reasons: 1, fiber entanglement: neuronal fibers are thin and often intertwined, making it difficult for existing segmentation methods to defferenciate and delineate their skeletal trajectories; 2, long-range discontinuities: biological images frequently contain regions with low signal-to-noise ratios, making long-range skeleton tracing prone to breaks. These errors can substantially distort the inferred neuronal topology.
- To address this, I propose a pixel-embedding model that reduces the errors. In addition, I develop a quantitative evaluation framework for measuring reconstruction errors in fiber skeletons.

Efficient Gridless Wideband DoA Estimation From Many Frequencies
06/2024 ~ 10/2024, Imperial College London
- This project develops a theoretical method for estimating the Direction of Arrival (DoA) of radio signals. We achieve accurate estimation for multiple sources and multi-band signals from a single snapshot, while significantly reducing computational complexity.
- This technology is applicable to 6G and Integrated Sensing and Communications (ISAC).
- The key theories include: Nonconvex Low-rank Hankel matrix Completion (NLHC), Proximal Dogleg Opportunistic Majorization (PDOM), Multiple Signal Classification (MUSIC)
