I am a PhD student in Electrical and Computer Engineering (ECE) at Purdue University, West Lafayette, IN. Previously, I worked for over 5 years as a Maintenance Engineer in a manufacturing facility in Pakistan, where I developed a strong interest in Machine Learning.

🔬 My Research Focus

• 🔄 Solving inverse problems using diffusion models as priors.
• 🧠 Modeling the auditory cortex in squirrel monkeys using pretrained deep learning models.
  Manuscript: Deep Neural Networks Explain Spiking Activity in Auditory Cortex

🌟 Interests
