Experience

  1. Research Assistant (Supervised by Dr. Laurel Carney)

    Carney Lab
    • Developed receptive-field encoding models to predict extracellular IC single-neuron responses with frequency and amplitude modulation tuning features (MATLAB).
    • Implemented MLP, CNN, and CKAN models to predict neural activity from single-trial data, enhancing model robustness over traditional trial-averaged approaches.
    • Analyzing acoustic stimuli signals with signal processing techniques including cochlear filterbanks etc.
  2. Research Assistant (Supervised by Dr. Christopher Kanan)

    kLab
    • Conducted multidimensional quantitative analysis of color representations in SOTA computer vision models and the fMRI responses of human visual cortex (Python).
    • Performed Representational Similarity Analysis (RSA) to assess the alignment of computer vision model representations with human perception, evaluating alignment using Pearson’s r and Spearman’s ρ and contextualizing the results with a leave-one-subject-out noise ceiling analysis.
  3. Summer school research

    Neuromatch
    • Analyzed large-scale calcium imaging data from 10,000 neurons in the mouse visual cortex to characterize functionally coherent neuronal ensembles engaged during stimulus events.
    • Applied Non-negative Matrix Factorization to reduce high-dimensional neural activity into 10 low-dimensional“neural factors,” identifying functionally coordinated neuronal assemblies that are spatially clustered within the cortical architecture.
    • Built an XGBoost model using neural factor activity to predict pupil size dynamics, achieving 90.3% accuracy on test data.
  4. Research Assistant(Supervised by Dr. Furao Sheng)

    State Key Laboratory for Novel Software Technology, Nanjing University
    • Developed a framework to convert Artificial Neural Networks (ANNs) to Spiking Neural Networks (SNNs), translating continuous neural signals into sparse, spike-based computation for reduced energy consumption (Python).
    • Investigated brain-inspired mechanisms like Surrogate Gradient Learning and Temporal Encoding to enhance the efficiency and accuracy of converted SNNs for potential on-chip applications.
  5. Software Engineer

    Shenzhen Kingdom Technology Co., Ltd–
    • Developed a framework to convert Artificial Neural Networks (ANNs) to Spiking Neural Networks (SNNs), translating continuous neural signals into sparse, spike-based computation for reduced energy consumption (Python).
    • Investigated brain-inspired mechanisms like Surrogate Gradient Learning and Temporal Encoding to enhance the efficiency and accuracy of converted SNNs for potential on-chip applications.

  7. Hierarchical Transformers for Multi-Document Summarization

    course project for Natural Language Processing(A)
    • Designed and evaluated a hierarchical Transformer model to address cross-document structure in multi-document summarization, overcoming the redundancy and lack of global coherence typical of flat-sequence processing.
    • Built a two-stage framework, replacing an LSTM ranker with a BERT-based encoder to jointly encode title-paragraph pairs and improve salient paragraph extraction.
    • Developed global Transformer layers with multi-head pooling and inter-paragraph attention to enable effective context fusion across documents.
    • Achieved a ROUGE-1 score of 11.11 using the BERT encoder, significantly outperforming the LSTM baseline and demonstrating improved content coverage and relevance.
  8. Backpropagation vs. Prospective Configuration in Neural Networks

    course project for Advanced ComputationalNeuroscience(A)
    • Evaluated the performance of Backpropagation in CNNs versus Prospective Configuration in Predictive Coding Networks (PCNs) on CIFAR-10 image classification and target alignment tasks.
    • Developed and trained CNN and PCN models, achieving 64.96% accuracy with CNNs (BP) on CIFAR-10 and demonstrating lower test error for PCNs under specific conditions.
