OPENINGS FOR GRADUATE AND UNDERGRADUATE STUDENTS, AND POST-DOCTORAL FELLOWS (updated in February 2017)
Starting dates are Sept., May or Jan. 2017-2018, or on a rolling basis any time of the year. Most of the openings listed below are available immediately but not all will be filled. If you are looking to apply for a PhD degree or post-doctoral studies please contact me by email directly. Please attach your CV/resume (WITH GPA CLEARLY STATED) and your transcript, in pdf format. If you have received a NSERC or OGS graduate scholarship or have another funding source, please inform me of this.
Most of the projects are collaborative, with participants from multiple other disciplines, mainly in Medicine, Neuroscience, Chemistry, Molecular Biology, Cell Biology, Computer Vision and Robotics. Unique opportunities exist for joint student supervision with other faculty members in Electrical and Computer Engineering (Electromagnetics with Prof. George Eleftheriades, Photonics with Prof. Joyce Poon), in IBBME (Neural Engineering with Prof. Paul Yoo, Neurosurgery/Neuroscience Prof. Taufik Valiante, Neurology/Neuroscience Prof. Peter Carlen and others) and those in other departments (Computer Science/Vision Prof. Kyros Kutulakos, Chemistry/Sensors Prof. Michael Thompson, Medicine, Collaborative Program in Neurosciences, Institute of Medical Science, etc).
Please note that the training focus in our lab is on academic careers (future professorships), entrepreneurship (future co-founders and CTOs/CEOs of companies) and senior-level R&D positions in industry worldwide. For most of the listed positions we prefer applicants with excellent communication skills who take initiative, and who are proven leaders, problem-solvers, self-starters, and team players.
Competitively-funded and volunteer openings include the following research positions:
1. (NEW!) COMPUTATIONAL CAMERAS: Transport-Aware CMOS Image Sensors and Cameras Design: Seeing around the Corner and Beyond (two positions)
The main goal will be to study, design, and deploy a new class of computational cameras whose key property is that they are "transport-aware." Unlike conventional cameras which record all incident light, transport-aware cameras can be programmed to block some of that light, based on the actual 3D paths it followed through a scene. Transport-aware cameras use a programmable light source for illumination and a programmable sensor mask for imaging, and are a pioneering breakthrough in the field of computational photography, with diverse novel applications, as unimaginable as seeing around the corner!
Live video from a transport-aware camera can offer a very unconventional view of our everyday world in which refraction and scattering can be selectively blocked or enhanced, visual structures too subtle to notice with the naked eye can become apparent, and object surfaces can be reconstructed in 3D under challenging conditions well beyond the state of the art.
These capabilities will find new uses in many industrial, scientific and commercial applications such as: augmented and virtual reality (for gesture recognition and object recognition), self-driving cars, 3D printers and scanners, video games, biomedical imaging systems (such as endoscopy), material analysis, drones, robots, and industrial machine vision.
The applicants should have interest and ideally previous experience in some of the following areas:
1.1. analog and digital (mixed-signal) VLSI circuits design (e.g., CMOS imager circuits such as column-parallel amplifiers and ADCs),
1.2. understanding of device physics of photodetectors as well as their 3D structure photo-generated charge simulation and layout (e.g., pinned photodiode, photonic mixer device),
1.3. embedded systems: computer architecture and microprocessor IP on-chip instantiation and programming (e.g., using open-core microprocessor IP such as TI MSP430 or ARM),

This is a highly collaborative project with several research groups around the world (USA, Italy), including those specializing in photodetector design, time-of-flight imaging, computer vision, and robotics. There may be opportunities to travel internationally to top research centers in North America and Europe.

We are looking for talented, highly motivated individuals to help us analyze these data. Specifically, the candidate will develop machine learning algorithms for predicting the onset of seizures, detecting epileptogenic brain regions and for identifying optimum brain stimulation strategies.
