Experience

DEC 2025 — PRESENT Handshake United States · Remote
AI Fellow
  • Designed and refined prompts to evaluate large language models (LLMs), focusing on reasoning quality, bias detection and instruction adherence.
  • Conducted human-in-the-loop evaluations of model outputs to assess accuracy, fairness, consistency, and domain specific reasoning.
  • Annotated large-scale text and video data, including detailed frame-level and cross-video analysis to capture visual changes and motion patterns across sequences.
JUN 2023 — DEC 2023 PES University Bangalore, India
Research Assistant
  • Developed a CNN-Transformer multimodal model to generate natural language metaphors from images by learning source-target domain mappings and aligning visual features with semantic concepts using cross-modal attention.
  • Applied multi-task learning with metaphor type, sentiment, and intent to improve generation quality, evaluated model performance using BLEU and BERTScore, along with qualitative analysis of interpretability, and semantic alignment.

Projects

PROJECT 01
BiLSTM-CNN With Attention For Remaining Useful Life Prediction In Turbofan Engines
TensorFlow · scikit-learn

Hybrid deep learning model combining BiLSTM, Transformer, and CNN architectures to estimate the Remaining Useful Life (RUL) of aircraft engines using the NASA C-MAPSS dataset. The model incorporates CBAM attention to enhance focus on key sensor features, positional encoding to preserve the temporal structure of sensor sequences, residual dilated convolutions to capture long-range dependencies, and transformer blocks for contextual sequence modeling, achieving average RMSE of 18.88.

PROJECT 02
Crowd Behavior Anomaly Detection in Surveillance Videos
PyTorch

Weakly supervised Multiple Instance Learning (MIL) framework for crowd behavior anomaly detection in surveillance videos, leveraging I3D-based spatio-temporal features extracted from RGB and optical flow streams. Utilizes multi-stream neural architecture, incorporating attention, residual connections, dropout, and layer normalization, achieving an AUC of 0.9022 and outperforming baseline classifiers in precision-recall balance.

PROJECT 03
Spatiotemporal Analytics and Pattern Mining in Urban Complaints
scikit-learn · NumPy · Pandas

Data mining and analytics on NYC 311 service requests, involving large-scale preprocessing, feature engineering, and exploratory analysis across geography, time, and socioeconomic factors. Applies clustering, contrast pattern mining, and co-occurrence analysis to identify borough-level complaint signatures, localized hotspots, and cascading complaints. Includes an anomaly detection framework using rolling statistical baselines to identify event-driven complaint surges, and predictive models for complaint volume and resolution time.

PROJECT 04
AI-Powered Diagnostic Support Tool
Node.js · React

Retrieval-Augmented Generation (RAG) system over PubMed records and the OpenAI API to generate disease predictions, and recommend medical tests and treatments based on patient symptoms, demographics, and medical history, incorporating agentic AI for context-aware reasoning and improved diagnostic accuracy.

PROJECT 05
Vehicle Detection and Classification
TensorFlow · OpenCV

SSD-Mobilenet V1-based traffic monitoring system to detect, count, and classify vehicles in real-time, addressing need for efficient traffic control. Implemented vehicle color and speed prediction, storing images of detected vehicles, and logging detection data to a CSV file for analysis.

PROJECT 06
Evaluating Traditional and Ensemble Learning Techniques for Churn Prediction
scikit-learn · NumPy · Pandas

Built and evaluated multiple machine learning models to predict customer churn using a telecom dataset. Applied feature engineering and preprocessing, and benchmarked classifiers including Logistic Regression, SVM, Decision Trees, Random Forest, Gradient Boosting, and ensemble methods.
