My name is Pavel Dolin. I’m a 4th-year CS PhD student and Dean's Fellow at Arizona State University, advised by Visar Berisha and Gautam Dasarathy. I apply statistics and ML theory to guide practical advances in AI/ML algorithms and architectures, with a current focus on reliability, scaling laws, and synthetic data generation. My previous publications include post-deployment monitoring for AI-based digital health (NeurIPS 2025), LLMs’ reasoning about actions and effects (ICLR 2025), and exploration of LLM safety and over-defensiveness (ACL 2024).

Outside of academia, I contributed to researching and architecting an LLM routing pipeline for an AI startup Aisera as an AI/ML research intern in the summer 2025. Before the PhD program, I also spent several years as an ML Engineer at an NLP startup Spiketrap, now part of Reddit.

Prior to Spiketrap, I obtained a BS in Physics from UC Santa Barbara, where I also conducted research in computational materials science, predicting material properties with statistical and ML methods, culminating in a journal publication.

INDUSTRY EXPERIENCE

Aisera

AI/ML Research Intern.

May 2025 - August 2025 | Santa Clara, CA

• Researched and architected a fast inference LLM routing pipeline that reduced baseline serving costs by 50% while maintaining the same accuracy. Led the engineering effort for a production-grade routing pipeline
• Fine-tuned transformer models in PyTorch using PEFT (LoRA/QLoRA, adapters) and selective fine-tuning (layer freezing, last-layer fine-tuning)

Spiketrap (NLP startup acquired by Reddit)

ML Engineer

Feb 2020 – Aug 2022 | San Francisco, CA

Received ML Engineer III (IC3) offer from Reddit after Spiketrap's acquisition; declined to begin PhD at ASU

RESEARCH:
• Lead research on Twitch chat sentiment detection and neologisms (emotes) understanding. Created an unsupervised framework, outperforming the previous benchmark by 7.36% points. First author publication.
• Lead research on Twitch "Hateful Raids" (cyberharassment phenomenon) detection and resolution. Successfully created a dataset and an ML + rule-based classifier for raid detections and hate bot/user flagging

ENGINEERING:
• Served as a lead engineer for end-to-end development and deployment of listed ML projects below:
• Topic Quality Project: Designed, trained, and deployed a topic quality model with custom metrics; built a retraining pipeline for drift handling and integrated into production ML infrastructure
• Twitter Handles Ads: Designed, trained, and deployed an end-to-end ML pipeline using a lexicon- and embedding-based model to identify semantically similar Twitter handles from seed accounts and their followers
• Text Summarization Project: Researched and evaluated models for summarizing user reviews, balancing cost and quality to select optimal architectures. Built a cost-efficient end-to-end pipeline and owned the full lifecycle
• Lead engineer for Notifications Project. Collaborated with multiple teams across the company to architect and ship a customizable, real-time notification service for clients. Designed the end-to-end pipeline, databases, REST APIs, architecture of the service, pipelines, fetching, storing, and processing of data. Fully implemented all the backend and was a supervisor for the frontend

PERSONAL

I love traveling and outdoor adventures: hiking, climbing, camping, off roading, occasional backpacking - visit my Instagram.

Salsa dancing is always a blast! Noodling on a guitar is a good way to unwind. Been trying sing more lately too, the neighbors are either clapping or hitting their heads, not sure yet.

I'm fluent in Russian. Been trying to catchup on my Russian Classics that I should've read years ago :)

I am a pacifist. I think any armed conflict is a terror that could have been prevented with proper diplomacy and reason.
