Arya Bakhtiar
I am student at UC Berkeley studying in the college of Electrical Engineering and Computer Sciences (EECS) and Molecular-Cellular Biology (MCB).
At Berkeley, I am currently doing research in the Berkeley Artificial Intelligence Research (BAIR) Lab, working with Amir Bar, Ph.D. and Professor Trevor Darrell.
I am also in the Mobile Sensing Lab, working with Alben Bagabaldo, Ph.D. and Professor Alexandre Bayen.
In addition, I am a part-time research intern at the Newman Lab, collaborating with Jeremy D'Silva, Ph.D. and Professor Aaron Newman.
Previously, I was an undergraduate researcher at the Sandler Neuroscience Building at UCSF, where I was advised by Dr. Roland Henry.

EgoPet: A pet’s-eye view of the world for learning animal behavior
Amir Bar, Arya Bakhtiar, Antonio Loquercio, Jathushan Rajasegaran, Danny Tran, Yann LeCun, Amir Globerson, Trevor Darrel
Submitted to CVPR 2024
Project Page (Coming Soon) | Code (Coming Soon)
I co-founded EgoPet, an extensive dataset comprising over 84 hours of egocentric videos activities and behaviors of various animals.
This project involved tasks such as object detection and frame assessment, crucial for improving locomotive performance in the Unitree A1 robotic dog and mirroring animal intelligence and interactions.
Our findings and methodologies culminated in a publication submitted to the IEEE / CVF Computer Vision and Pattern Recognition Conference (CVPR).

Empirical evaluation of diverted traffic by signal coordination
Alben Bagabaldo, Arya Bakhtiar, Preston Fu, Alexander M. Bayen
Publication in Progress, Janurary 2024
Project Page (Coming Soon) | Code (Coming Soon)
I investigated traffic signal timings in the Mission San Jose District of Fremont, California, using a validated and calibrated microscopic traffic simulation model considering 2019 demand data.
Employing a dynamic traffic assignment microsimulation model with a logit-based route choice model, I examined the effects of both uncoordinated signal timings and the strategic reconfiguration of traffic signals on Mission Boulevard, one of Fremont's primary arterial roads.
Through my analysis, I discovered strategic reconfigurations of certain signal coordination strategies that could significantly redirect traffic flow, effectively alleviating congestion at targeted intersections and enhance the overall network performance.

SLASER & JDE Analysis For MRI
Arya Bakhtiar, Roland Henry, Amit Akula
Presented portion of research at the Berkeley Summer SURF 2019 Conference Event
Project Page | Code
I won a summer SURF fellowship by submitting a proposal to pursue an independent project. I developed software to track the concentration of specific metabolites, such as glutathione, using MRI images collected from patients diagnosed with Multiple Sclerosis. I presented part of my research findings to a summer research cohort.

Utilizing Graph Neural Networks with Spatial Transcriptomics Data
Arya Bakhtiar, Jeremy D'Silva
Summer 2023 - Current
I am investigating the spatial organization of distinct cell types in the tumor microenvironment and its impact on cell state and tumor progression. Utilizing Graph Neural Networks (GNNs), I am modeling complex cell interactions within tumors,
capturing nuances in cellular behavior. My work primarily employs PyTorch Geometric, a tool for deep learning on graph-structured data, to analyze and interpret these cellular networks.
Through this approach, I aim to unravel the intricate dynamics of tumor cells and their environment, contributing to advancements in cancer treatment strategies.

Exploring scRNA-Seq Data at Population Scale with GloScope
Arya Bakhtiar, Yiyan Hao, Will Torous, Hao Wang, Elizabeth Purdom
Fall 2023 - Current
I am conducting data extraction and enhancement on single-cell RNA sequencing (scRNA-Seq) information sourced from academic publications that studied diverse patient groups.
Utilizing both R and Python, I am developing scripts to perform comprehensive analyses on how individual cell differences influence patient characteristics.
In addition, I am working in close partnership with two doctoral candidates, taking an active role in periodic updates for the GlyScope initiative.

Uncovering Biological Insights in Spatial Transcriptomics Data in Mouse Brain Aging
Arya Bakhtiar, Reza Abbasi-Asl
Presented portion of research to lab seminar at Stanford, Spring 2023
Project Page | Code
At the Abbasi Lab, I leveraged deep autoencoders, non-negative matrix factorization (NMF), and semi-supervised deep CNNs to uncover significant and previously undiscovered spatial genomic patterns in complex brain images, which included a range of modalities
such as fMRI and gene expression data. Additionally, I designed and validated interpretable machine learning frameworks and statistical tools, which revolutionized our understanding of cell types, their spatial arrangement, local gene networks,
and revealed new patterns in complex brain images across human and mouse models, significantly advancing our knowledge of brain function, development, aging, and their implications for patient health and clinical decision-making.

Utilized and Improved PathFX pipeline at the Lab for the Understanding of Network Effects (LUNE)
Arya Bakhtiar, Jennifer L. Wilson
Project Page | Code
I initiated a research project with Dr. Jenifer Wilson at UCLA using PathFX, a data-driven algorithm that predicts drug adverse effects using protein-protein interaction networks.
After training against several tissue and cell type specific models, I developed modifications to the algorithmic pipeline that significantly enhanced PathFX’s capacity to predict drug-induced side effects.
My analytical efforts led to the reevaluation of several drug pathways, a crucial step in unveiling new therapeutic strategies and drug repurposing.

Teaching
During my time at UC Berkeley, I served as a AI and course assistant tutor for several of the EECS and MCB courses.
I spent 5 semesters assisting MCB C100A: Biophysical Chemistry - Physical Principles and the Molecules of Life for Professor John Kuriyan (now at Vanderbilt University) and Professor David Savage.
