LLM Research @ Susquehanna
Call me Ansh Nagwekar (ahnsh nah-GWAY-kar). You've just boarded my life's figurative Pequod. No white whale in sight, but I'm still looking…
Let's rewind: I grew up in sunny San Jose, CA and spent high school at Bellarmine (BCP) tinkering with robots, playing ice hockey, hiking with my Boy Scout troop, and eating an unholy number of curly fries in the cafeteria. Somewhere in there, especially during the long, remote, book-heavy stretch of COVID, I fell into the habit of seeing building as both an art and a science — a dualist little epiphany that's stuck with me ever since. That's what influenced me to major in an interdisciplinary program at Penn called NETS that fused computer science, mathematics, and economics with applications to networked systems (such as the Internet, capital markets, search engines, etc.). It eventually got succeeded by the Artificial Intelligence degree (I guess it was the first of many things to get replaced by AI).
Right now, I'm a machine learning researcher at Susquehanna, applying frontier developments in AI to our news-driven trading strategies. I joined as an intern in 2024 and went full-time in 2025 on our flagship options market-making desk. My early work there was building the systematic trading platform behind long horizon volatility-based signals: market-making strategy feeds, trading parameter harness that enable strategies to adapt intraday, and the real-time monitoring around them. Working that close to the strategy critical path changed how I think about pursuing applied research — an idea is only interesting to me if it surfaces itself in the problems we face in real time. It also reinforced the dualistic view of my work: the craft of a system and the truth of its numbers have to hold up at the same time or neither one matters.
Before that I moved through some fairly different worlds. At Ion Protocol I was a blockchain research engineer writing Go, Rust, and Solidity for DeFi lending markets and yield oracles. At Tesla, I worked on pricing and configuration software across the Tesla product lineup and supercharger network, where I used enough applications of graph traversals to perhaps compensate my algorithms professor for the hours he spent watching me fall asleep or stare blankly at the chalkboard. Before either of those, I was a founding engineer at VO2 Fans, a platform my friends and I came up with that would “tokenize” the sports fan experience. It was a pretty wild time: picture a bunch of college kids trying to create a secure Web3 platform that would transact earnings for the most engaged fans in crypto, while also trying to partner with athletes (imagine explaining NFTs to MMA stars like Tony Ferguson). We raised a $350k seed, went through Techstars' 2022 sports accelerator in Indianapolis, and eventually sold the platform away before we came back to school.
After trying out startups and blockchain, I decided to dedicate the rest of my studies to understanding and advancing the frontier of deep learning. So I enrolled in the Accelerated Master's in Computer Science and spent the extra credits researching neural network optimization with Nikolai Matni's Unstable Zeros group at Penn's ASSET Center. Some ideas that we deeply explored, such as layer-wise preconditioning, higher-order optimization algorithms, and connections to statistical learning theory, surface in our ICML 2025 paper and my graduate thesis, which was primarily written as a “cookbook” for the theory of training large neural networks at scale. Alongside that, I spent three years as an investment researcher at Open Core Ventures, where I provided technical due diligence on 250+ open-source projects, which is where most of my instincts about what good software looks like actually come from.
What ties all of this together is how quickly I pick up new technologies and product spaces — and how completely I fall into them once I do. News trading, options market-making, DeFi protocol design, EV supercharger pricing systems, optimization theory: different worlds, but I've never had trouble getting obsessive about the internals of whatever I'm in. These days that curiosity is pointed at making large models train and serve efficiently, and understanding why the optimizers we already use work as well as they do: a question that's equal parts art and science.
Deep Learning Research
Studied optimization theory and its applications to deep learning in Nikolai Matni's Unstable Zeros group. Published work relating theoretical results from statistical learning and optimization algorithm design to efficient representation learning in deep networks via layer-wise preconditioning.
Academic Research Projects
Master's-level courses where the deliverable was an original research project rather than a final exam.
Auto-bidding theory generally assumes click-through rates are known in advance; this treats CTR estimation as part of the problem and asks what that assumption costs in liquid welfare and individual regret. We developed incentive-compatible allocation algorithms for repeated single-slot ad auctions among budget-constrained bidders, covering both the myopic case, where a bidder optimises only the current round, and the non-myopic case, where it plays across all of them. The myopic algorithm reaches optimal liquid welfare over a long enough horizon, and simulations sweep a hybrid objective λ interpolating between pure value- and utility-maximisation.
An empirical study on CIFAR-10 of how architectural choices shape the spectral and information-theoretic structure of a VAE's compressed representations. Standard architectures turn out to produce isotropic latent spaces, with variance spread uniformly across every dimension, while task-specific supervision measurably sharpens that structure and end-to-end classifiers learn more informative representations still. Mutual information analysis suggests why: purely reconstruction-driven training can diffuse the features that actually matter, where a task-oriented objective tends to preserve them.
Medical cost forecasting needs calibrated uncertainty for financial planning and rarely quantifies it, so we applied conformal prediction to the problem. The work reviews the underlying theory — calibration, quantile regression, and threshold-calibrated guarantees — then builds a framework that pairs it with standard ML models to produce statistically rigorous prediction intervals. It holds the target coverage rate across six demographic subgroups defined by gender and region while adapting interval width to local uncertainty, which makes fairness a coverage constraint rather than an afterthought.

“Reality is far more vicious than Russian roulette. First, it delivers the fatal bullet rather infrequently, like a revolver that would have hundreds, even thousands of chambers instead of six. After a few dozen tries, one forgets about the existence of a bullet, under a numbing false sense of security. Second, unlike a well-defined precise game like Russian roulette, where the risks are visible to anyone capable of multiplying and dividing by six, one does not observe the barrel of reality. One is capable of unwittingly playing Russian roulette — and calling it by some alternative ‘low risk’ game.”
