Sara Madjdi-Sorkhabi

Computer Science & Statistics Student | Aspiring Quant Researcher

I am a senior at California State University, Northridge (B.S. in Computer Science and Statistics, expected May 2026) focused on quant research, data science, and data analytics. I enjoy building reproducible data pipelines, developing statistical and machine learning models, and turning large datasets into practical decisions.

ASL Sign Language Interpreter

Building a real-time computer vision system with Python, OpenCV, and PyTorch to classify ASL gestures and convert prediction translations from text to speech output.

View project details

Built a custom ASL Sign Language Dataset using OpenCV and MediaPipe, developed a real-time gesture pipeline, trained classifiers on labeled hand-sign data, and evaluated performance with iterative preprocessing and augmentation to improve robustness.

AI Mentorship Platform for Intro to Mechanical Engineering

Led a 10-student team to build a mentorship platform with Flask, React, and SQL for personalized support in Intro to Mechanical Engineering.

View project details

Built a course-restricted assistant for ME101 using a RAG pipeline so students can ask ChatGPT-style questions answered only from approved CSUN course materials. Added a quiz-generation tab that creates multiple-choice practice questions by topic from the same uploaded materials, and developed a personalized analytics dashboard that tracks quiz performance metrics to help students identify weak areas.

Multi-Criteria Shortest Path Optimization

Extended Dijkstra's algorithm with dual edge weights in Java/Python to evaluate trade-offs in multi-objective routing.

View project details

Compared runtime and quality trade-offs against standard shortest-path methods and documented how multi-objective constraints affect route selection and complexity.

Early Detection of Cocoa Seed Infection

Developing computer vision models in Python and PyTorch to detect early-stage cocoa seed infection with EfficientNet architectures.

View project details

Applied image preprocessing and augmentation workflows to improve model performance and evaluated architecture-level trade-offs for early detection accuracy.

NSF Higher Criticism Research

Implemented statistical computing methods in R for large-scale multiple testing and high-dimensional inference.

View project details

Built bootstrap resampling workflows from scratch to support Higher Criticism research and contributed to computationally efficient methods for modern statistical inference.
