Recently graduated with a Master of Science in Applied Mathematics, Vaughn is pursuing a first industry career role in research or machine learning\. Vaughn’s strengths combine mathematical theory, neural\-network implementation, and experimental validation, with particular depth in adversarial robustness and randomized smoothing\. Vaughn led an adversarial\-robustness research project through theory, implementation, and experiments, resulting in a presentation at NeurIPS 2025\. In current research, Vaughn is developing a novel PyTorch randomized\-smoothing method using a mixed Gaussian distribution and studying the effectiveness of layerwise randomized smoothing\. The mixed\-Gaussian work was validated through mathematical proofwork and statistical experimentation and accepted for presentation at the Reliable ML Workshop in December 2025\. Vaughn also brings instructional, analytical, and cross\-functional experience from grading university courses, supporting the Gold Tree Solar Farm project, and improving financial\-data and accounting\-resource workflows at Plantel Nurseries Inc\. Vaughn works best with initial mentorship, followed by independent ownership and open communication\. ## Highlights - Conducts adversarial\-defense research for neural networks at California Polytechnic State University–San Luis Obispo\. - Developed a novel PyTorch randomized\-smoothing method using a mixed Gaussian distribution\. - Researches the effectiveness of layerwise randomized smoothing\. - Validated mixed\-Gaussian randomized\-smoothing results through mathematical proofwork and statistical experimentation\. - Had mixed\-Gaussian research accepted for presentation at the Reliable ML Workshop in December 2025\. - Led an adversarial\-robustness research project across theory, implementation, and experiments\. - Presented adversarial\-robustness research at NeurIPS 2025\. - Graded Calculus II \(MATH 143\) labs and assignments for more than 70 students at California Polytechnic State University–San Luis Obispo\. - Provided detailed assignment and quiz feedback to Calculus II students who were struggling\. - Graded Energy for a Sustainable Society \(BRAE 348\) labs and assignments for more than 70 students at California Polytechnic State University–San Luis Obispo\. - Provided detailed assignment and quiz feedback to Energy for a Sustainable Society students who were struggling\. - Cleaned and analyzed financial datasets at Plantel Nurseries Inc\. using Excel and Basic scripts\. - Collaborated with Plantel Nurseries Inc\.’s CFO and Operations Manager to improve internal accounting and resource\-management structure\. - Collected and analyzed shadow data for the 2022 SURP Gold Tree Solar Farm Project to model the solar farm and help prevent blackouts\. - Collaborated with faculty and peers on the Gold Tree Solar Farm Project using Excel, fabrication tools, and surveying devices\. - Earned a Master of Science in Applied Mathematics from California Polytechnic State University–San Luis Obispo\. - Earned a Bachelor of Science in Mathematics and Computer Science from California Polytechnic State University–San Luis Obispo\. ## Experience - **Adversarial Defense Research at California Polytechnic State University\-San Luis Obispo** (2025\-03\-01–present) — ● Machine learning research on adversarial defense for neural networks, creating a novel method of randomized smoothing in Pytorch using a mixed Gaussian distribution\. ● Current research focuses on the effectiveness of a layerwise randomized smoothing method\. ● Validated results through mathematical proofwork and statistical experimentation mixed Gaussian research was accepted for presentation at the Reliable ML Workshop \(Dec 2025\)\. - **Grader at California Polytechnic State University\-San Luis Obispo** (2025\-04\-01–2025\-06\-01) — ● Graded labs and assignments for 70\+ students in Calculus II \(MATH 143\)\. ● Provided detailed feedback to help students who were struggling on their assignments and quizzes\. - **Office Intern at Plantel Nurseries Inc\.** (2024\-06\-01–2024\-08\-01) — ● Cleaned and analyzed financial datasets using Excel & Basic scripts to help fellow employees keep track of their respective work\. ● Collaborated with CFO and Operations Manager to upgrade the internal structure for accounting and resource management\. - **SURP 2022 Gold Tree Solar Farm Project at California Polytechnic State University\-San Luis Obispo** (2022\-06\-01–2022\-09\-01) — ● Collected and analyzed shadow data to model the Gold Tree Solar Farm to prevent blackouts\. ● Collaborated with faculty and peers using Excel, fabrication tools, and surveying devices over the course of many hours\. - **Grader at California Polytechnic State University\-San Luis Obispo** (2022\-03\-01–2022\-06\-01) — ● Graded labs and assignments for 70\+ students in Energy for a Sustainable Society \(BRAE 348\)\. ● Provided detailed feedback to help students who were struggling on their assignments and quizzes\. ## Education - Master of Science \- MS, Applied Mathematics — California Polytechnic State University\-San Luis Obispo (2025\-01\-01–2026\-01\-01) - Bachelor of Science \- BS, Mathematics and Computer Science — California Polytechnic State University\-San Luis Obispo (2023\-01\-01–2025\-01\-01) - Incomplete \- Switched Majors, Mechanical Engineering — California Polytechnic State University\-San Luis Obispo (2020\-01\-01–2023\-01\-01) ## FAQ ### What does Vaughn do?
