Improved optimization algorithms for creating graphical representations of IT component webs that reduce edge overlapping and graph size by recursively shifting the positions of components’ child nodes and connection edge placements. Developed a back-end data system and web interface for real-time data filtering and sorting, complete with a RESTful API for efficient system data management. It treads linked lists and trees of IT data and packages them into JSON files in user-requested forms to be received and displayed by the Javascript front-end, supporting hundreds of thousands of components.Set up and managed AWS VM instances, CyberArk integrations, and the Microsoft Intune Policy Manager.

Developed an account generation program and analyzed email verification data using NumPy to reveal a security flaw in 70% of the leading US websites, resulting in a publication in HAISA’23.

CSE 548/Graduate AlgorithmsAssist in teaching graduate-level concepts in greedy algorithms, dynamic programming, probabilistic algorithms, the disk access model, and graph algorithms.Collaborate with the instructor to develop problem sets, exams, and instructional materials.Lead discussion sections and hold office hours to support student learning.

File Systems and Storage Lab (FSL).Developed a custom I/O scheduler in the Linux kernel to prioritize block device requests based on predicted latencies.Utilized linked lists and max heaps for request management and spinlocks for thread-safe synchronization.Integrated a machine learning model to predict and reorder I/O requests, reducing average I/O latency by up to 50%, thereby enhancing system responsiveness and optimizing disk I/O performance.

Program Analysis, Software Testing, and Applications Laboratory (PASTA Lab).Conducted an empirical study (DATE-SMELLS) to systematically identify common date/time-related issues in open-source repositories using Python, JavaScript, and Java by leveraging tools like Sourcegraph and GitHub's GraphQL API to analyze issues, commits, and developer discussions.Developed a taxonomy to classify these date/time-related bugs, raising awareness among software engineers by documenting and disseminating findings in a catalog of bug patterns.Created an automatic bug-finding tool (DATE-COP) by implementing static analysis with CodeQL and dynamic linting techniques, integrated into a GitHub bot to discover and report date/time-related bugs at scale in open-source projects.

Committed to empowering students and adults traditionally underrepresented in personalized tutoring and mentoring. Offered one-on-one STEM tutoring in Physics, Calculus, and more to Bronx students, fostering their journey into the professional world with personalized support and guidance.

Analyzed single-cell RNA sequencing data and differentiation markers from mutant mice using Excel to uncover the cell regulatory networks that control normal and diseased skin states, resulting in a publication in JID.
