July 2020 - Former Teuscher Lab Summer Intern Accepted to Yale and Completing Internship at CNN
High schooler Raja Morena did an internship in Teuscher lab last summer before being admitted to Yale for his undergrad studies. He is also doing an internship with Anderson Cooper 360 this summer. In his own words:

At Teuscher Lab, I designed and implemented algorithms to automate the analysis of teaching and learning activity in a college classroom. I tested and documented the work for Professor Teuscher to use in a grant proposal. I also had a wonderful time getting to know the other members of the lab, and leaned on a lot of its senior members for help and advice.

Doing research in Teuscher Lab was my first “real” work-during-working-hours job, and it helped me get used to being diligent and focused during my work day. A lot of the critical thinking and creative problem-solving skills I nurtured in the lab also help me now on AC360°. Moreover, Professor Teuscher helped me figure out that I want to continue using quantitative methods to solve interesting social problems in my education and beyond. I try to pay the generosity and kindness he showed me forward to the incoming first-years I mentor. I look up to Professor Teuscher as an example of how to be kind and welcoming to everyone — he took me in when I had nothing to offer but curiosity and a bit of elbow grease and helped me learn. I will always be grateful to him for that.

Here’s a little more about what I do at CNN:

I research breaking news stories and present my findings to our production team for use on air. 
I compiled an internal database for the booking team. 
I shadow our control room operations and pre-tapes. assist the APs/PAs, transcribe interviews, and investigate and pitch several stories per week.

The only thing I’d like to add is a big thank-you to Professor Teuscher

June 2020 - GPU-based Computation and Data Enabled Research and Education (G-CoDERE) at PSU

An interdisciplinary group of PSU faculty led by Feng Liu (CS) and comprising Christof Teuscher (ECE), Jay L Nadeau (Physics), Bruno Jedynak (Math+Stat), Steve L Reichow (Chemistry), and systems architect William Garrick (OIT Research Computing Manager and Architect) has been awarded a two-year, $395,926 NSF grant for a high-performance GPU-based computing cluster. The funding will allow PSU to acquire 20 GPU-enabled servers and storage. Specifically, the proposed infrastructure includes 4 nodes with 4 NVIDIA Titan RTX and 768 GB RAM, 16 nodes with 4 RTX 2080 Ti, 12 of which with 192 GB RAM and 4 with 384 GB RAM, and 480 TB usable storage. The requested resources will augment and enhance the existing computational resources at Portland State University and benefit researchers as well as students.

February 2020- Teuscher Lab summer interns accepted for MIT THINK Scholars Program

High schools students Ishaan Sinha and Owen Caverly wanted research experience so they reached out to some professors. Dr Teuscher agreed to have them intern in teuscher.:Lab last summer. Their experience helped them get accepted for the MIT THINK Scholars Program where they received a four-day all-expenses paid trip to MIT to meet professionals in their field of research, tour labs, and attend MIT's xFair. While there, they met a professor who is offering to fund their project, as well as invite them to his summer institute.

Their research project this summer was EyeHear: Smart Glasses for the Deaf and Hard of Hearing. Dr Teuscher connected them to some resources, such as an anechoic chamber and a loan of a Google Glass Explorer Edition. Great job Ishaan and Owen!

November 2019- ECE students published in Nature

Former ECE PhD student Walt Woods and ECE student Jack Chen have a Machine Learning article accepted and published in Nature. Editor's summary: Deep neural networks can be led to misclassify an image when minute changes that are imperceptible to humans are introduced. While for some networks this ability can cast doubt on the reliability of the model, it also offers explainability for networks that use more robust regularization.

July 2019 - Visiting Professor Stanley Rotman joins ECE department

ECE would like to welcome visiting Professor Stanley Rotman of Ben-Gurion University of the Negev in Israel. His research area is hyperspectral data analysis, taking images that (rather than having one spectral band (black and white images) or color (three spectral bands)) have hundreds of spectral bands and analyzing them. He hopes to combine this with the machine learning research of Dr Lipor.

June 2019 - ECE Visiting Professor Ephraim Suhir receives the IEEE Field Award in Electronics Packaging at the 69th IEEE Electronic Components & Packaging Conference in Las Vegas. The IEEE field awards are the highest in the specified technical areas.

“For seminal contributions to mechanical reliability engineering and modeling of electronic and photonic packages and systems.” 
With over 40 years of pioneering work in modelling and reliability engineering, Ephraim Suhir has enabled electronic packaging engineers to accurately predict stress in advanced packaged components for the design of more reliable devices. He was one of the earliest researchers to introduce the use of rigorous mechanics principles in electronic systems. His closed-form solutions have provided the electronics industry with invaluable tools for ensuring reliability and cost savings during the design process by eliminating errors early in the design process. He has applied his techniques to advanced components and packaged structures such as microelectronics, photonics, photo-voltaics, and thermoelectronic modules. Every serious mechanics practitioner and researcher in the electronics packaging field has been influenced by Suhir’s groundbreaking contributions.

May 2019 - Dr. John Lipor awarded NSF grant

Dr. Lipor's research will focus on the design, analysis, and deployment of algorithms for adaptively sampling the environment with mobile sensors. Phenomena such as harmful algae booms and wildfires regularly impact the Portland area and Oregon as a whole. In the latter case, a key task is understanding the spatial extent of airborne particulate matter resulting from fires. This research seeks to design algorithms that adaptively track this spatial extent while accounting for practical considerations, such as the time required to travel between sampling locations and the need to recharge the vehicle.

January 2019 - ECE students make it to finals of Cleantech Competition

Congrats to the ECE students who have made it to the finals of the Cleantech Challenge with their Living Window project!

From Stevie: Our project Living Window is being worked on by the members of Portland State Product Innovation (PSPI), a club at PSU, led by team members Stevie Taylor, William Lau, and Talya Naftali. The Living Window is a greenhouse inside of a wall with automation, phone app, hydroponics, and plumbing components among others. We plan to bring this project as far as possible within the Cleantech Challenge and InventOR should we make it that far, and beyond. Anyone interested in working on this project, or other projects, or want to find other people to work on your pet project with us should join a PSPI meeting which take place every Friday from 5:30pm-7:30pm in EB 421. Email to join the mailing list or ask for more details about PSPI or the Living Window.
