Undergraduate Research Students
Hao You, Mixed-Signal Design
My name is Hao You, and I am currently a third-year student at the University of Toronto majoring in Electrical engineering. I’ve started research on microelectronics under the supervision of Prof. Amirsoleimani for about a year. My main focuses now are on hardware acceleration through resistive memory and high-performance ADC. My current first and second projects mainly involve applying existing resistive memory devices on ADC by creating new hybrid ADC architecture to achieve high performance.
Xuening Dong, AI Hardware
My name is Xuening Dong and I am a first-year Master’s student at McGill University studying Electrical and Computer Engineering. I obtained my B.A.Sc Degree in Computer Engineering at the University of Toronto. The research work that I conducted under the supervision of Dr. Amirsoleimani focuses on harnessing the stochastic nature of memristive devices, performing numerical computations over memristive crossbars, and acceleration of in-situ training for deep neural networks.
Timothy Zhang, Neuromorphic Engineer
My name is Tim (Timothy) and I am currently a final-year student at McGill university studying Bioengineering! I have been researching under the supervision of Prof. Amirsoleimani for almost 2 years, specializing in algorithm-hardware co-optimized designs for biomedical applications. My first project involves using in-memory-computing technologies to achieve ultra-efficient spike sorting, and My second project involves designing a neuromorphic autoencoder for single-cell RNA sequencing data processing.
Muhammad Ahsan Kaleem, AI Hardware
My name is Muhammad and I am currently in my third year of Engineering Science at UofT,
majoring in Machine Intelligence and pursuing minors in Math and Robotics. I have been doing research under the supervision of Dr. Amirali Amirsoleimani since the summer of this year, and I have worked on 2 projects so far and am currently continuing work for a new one. Both of the projects that I have worked on so far involved researching ways of improving performance of memristive neural networks with non-idealities, by utilizing techniques such as ensemble methods and novel loss functions.
Tony Liu, AI Hardware
My name is Tony Liu and I am currently a fourth year student in the Engineering Science program at the University of Toronto specializing in Machine Intelligence. I have been working with Dr. Amirsoleimani for over two years in memristor crossbar software-hardware co design. In first project, I developed an optimization scheme for adjusting the input voltage pulse to minimize the degradation of the memristor crossbar’s memory and increase system longevity. In my second project, I created an stochastic input encoding to reduce the input voltage range and power consumption of the memristor crossbar system.
Ali Al-Sharaawi, AI Hardware
My name is Ali Al-Sharaawi third year undergraduate at the University of Toronto’s department of electrical and computer engineering. I have been working with Dr. Amirsoleimani for almost two years on development of co-hardware and software design. We developed a novel pruning algorithm for memristor crossbars to develop more efficient AI. In our recent work, we proposed a scheme that leverages singular value decomposition and low-rank approximation to generate all vectors needed to program a CNN onto a memristor crossbar-based accelerator.
