March 2021 - Dr. Bird's Department of Energy Grant

Dr. Bird and his Ph.D. graduate student, Dawei,  are busy using their Department of Energy research grant to create a new type of variable stiffness torsional magnetic spring for an ocean generator application. The rotary magnetic spring is composed of a new type of magnet configuration that allows it to create a linear change in torque with angle. The stiffness can be adjusted through axially shifting the rotors. The ability to change the stiffness will enable the ocean generator to resonant with the ocean waves frequency.

November 2020 - Dr. John Lipor's Recent Research 

  1. Dr. Lipor's student Wubin Sheng presented at the Asilomar Conference on Signals, Systems, and Computers this month. His work describes a novel, general framework for deep learning from pairwise comparisons (e.g., whether two images are of the same object or not). They provide a unified method for incorporating this information into clustering, semi-supervised classification, and supervised classification that outperforms competing methods for learning with limited supervision.
  2. Dr. Lipor's paper "Subspace clustering using ensembles of K-subspaces" was published in Information and Inference: A Journal of the IMA. They describe an ensemble-based algorithm for subspace clustering that provably achieves perfect clustering when the data satisfy standard regularity conditions and achieves state-of-the-art performance on several image recognition datasets.

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

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.
