OBJECTIVE

Looking for a full-time data scientist or ML/DL researcher position. Solid understanding of neural networks and hands-on experience in implementing and re-designing model architectures. Experience in domain-specific data processing. EXPERIENCE

COLUMBIA U TAUB: AD & AGING BRAIN FULL-TIME PAID RA Full-Time Researcher Dec 2019 - Present New York, NY Student Researcher Jan 2019 - Dec 2019 New York, NY Selected Project 1: DeepContrast, Image-to-Image Transform on MRI Skills: Python (Pytorch), image similarity metrics, linear regression, t-test, voxel-based analysis, ROC analysis, multiple comparison correction, Monte-Carlo Simulation, etc. Objective: Use Residual Att. U-Net to simulate the contrast enhancement given by the most widely used yet harmful contrast agents in MRI from one single input.

• Phase 1. Image synthesis. ISBI’20 best paper final list, ISMRM’20 Oral

• Phase 2. Clinical Validations. Nat. Biomed. Eng Under Review Replicated clinical findings (Aging, Alzheimer’s, Schizophrenia) published on Nat. Neurosci ’13, Nat. Neurosci ’14, Biol. Psychiatry ’20 using the simulated contrast on large-scale datasets (177, 200, and 92 scans respectively).

• Phase 3. Extensions. Alzheimer’s classification using the simulated contrast

(implemented 4 architectural flavors of VGG-19BN), and several other studies. Selected Project 2: J-Difference Editing Toolkit (JET) GitHub Release V1.0 Skills: MATLAB, spectroscopy data processing, spectral registration and fitting, etc. Objective: Write an end-to-end toolkit for loading, aligning and quantifying metabolites from MRS data. JET is helping researchers in multiple institutions. Selected Project 3: Cell Segmentation and Tracking ArXiv’20 Skills: Python (Pytorch), detection, tracking, segmentation, shape feature analysis, etc. Objective: Multi-object tracking and localization on cell cultures for biology studies. INDEPENDENT PROJECT

Carbon Emission Predictors Energies’20

Skills: Python (Keras), time-series forecasting, ANOVA, post-hoc Tukey’s HSD test, etc. Employed FFNN, LSTM and Transformer to forecast carbon emission data. Identified shortwave radiation as the climate driver most predictive of carbon emission. Movie Recommendation System

Skills: Spark SQL, Spark MLlib, Elasticsearch, Alternating Least Squares etc. Present the potentially interesting movies to an user given his/her previous ratings. OTHER RESEARCH EXPERIENCE
