Pushkal Mishra

PhD in ECE at UCSD

I am a PhD student at University of California San Diego (UCSD) working in the innovative Wireless Communication, Sensing and Networking Group (WCSNG) advised by Prof Dinesh Bharadia.

My research interest lies in developing scalable deep learning systems that perceive and reason about the physical world, with a focus on autonomous driving. Currently I'm building radar foundation models and sensor-fusion frameworks that unify simulation with real-world data for robust scene understanding. A core theme is for a modular architecture that integrates diverse sensors (radar, LiDAR, cameras) while improving interpretability and generalization.

I completed my undergraduate studies at Indian Institute of Technology Hyderabad, where I earned my B.Tech in Electrical Engineering with a minor in Computer Science. During my undergraduate years, I was fortunate to be advised by Prof. Aditya Siripuram and Prof. Ayon Borthakur on projects spanning graph learning, neural networks, and signal processing.

Besides work, I enjoy playing a lot of sports such as ultimate frisbee, swimming and badminton. I love listening to music and my favourite activity to unwind is to drive! I also represented my squash team at multiple competitions such as Milan and Diesta during my undergraduate.

Publications

I am broadly interested in the intersection of sensing, machine learning, real-world perception systems and engineering. I am very passionate about developing scalable deep learning systems that have real-world impact and drive innovation.

C-Shenron VTC

A Realistic Radar Simulator for End-to-End Autonomous Driving in CARLA

Satyam Srivastava*, Jerry Li*, Pushkal Mishra*, Kshitiz Bansal, Dinesh Bharadia
IEEE VTC Fall 2025

We present C-Shenron, a radar simulation framework integrated into CARLA that generates realistic radar measurements by fusing LiDAR and camera data. Our framework supports configurable radar parameters and demonstrates that radar-camera fusion models achieve performance equivalent to LiDAR-camera baselines on CARLA leaderboard metrics.

C-Shenron Demo

Demo: Radar Simulator for CARLA

Pushkal Mishra, Satyam Srivastava, Jerry Li, Kshitiz Bansal, Dinesh Bharadia
ACM SenSys 2025

C-Shenron is the first realistic radar simulator that utilizes LiDAR and camera sensors to generate high-fidelity radar ADC measurements from physics-based modeling. We demonstrate improved performance in end-to-end driving scenarios and aim to rekindle interest in radar-based self-driving research.

SPELA Learning

Learning Using a Single Forward Pass

Aditya Somasundaram*, Pushkal Mishra*, Ayon Borthakur
TMLR 2025 Best Poster Award at NYAS

We propose SPELA, a learning algorithm that operates with local loss functions using a single forward pass, significantly reducing memory and computational requirements. SPELA eliminates gradient propagation while demonstrating competitive performance with backpropagation on standard benchmarks, making it ideal for resource-constrained edge AI applications.

Graph Inpainting

Inpainting-Driven Graph Learning via Explainable Neural Networks

Subbareddy Batreddy*, Pushkal Mishra*, Yaswanth Kakarla, Aditya Siripuram
IEEE Signal Processing Letters 2024

We propose an algorithm for simultaneous data restoration and graph structure learning using an interpretable neural network designed from unrolling framework. Our closed-loop feedback mechanism guides graph learning based on inpainting performance, achieving robust results under noisy conditions on sensor network datasets.
