IDEAL Attends IDETC 2023

We attended the International Design Engineering Technical Conferences (IDETC) 2023 in Boston Park Plaza, Boston, Massachusetts. The conference was held between August 20-23, 2023. In total, IDEAL members presented 3 papers which are shown below. Our members also collected few awards during the conference. Yigitcan received the “Paper of Distinction” recognition,  Jie and Joy received the 3rd place in the ASME-CIE Data Hackathon on “Automating Material Selection for Product Design”,  and Tuba received the Broadening Participation (BPart) Fellowship and Mentorship award.

Prof. Chen participated in a panel under the topic “Digital Twin for Smart Manufacturing”, which aimed to  discuss challenges and technical approaches in the digital twin area.

Prof. Chen receives NSF BRITE Fellow Award

Congratulations to Prof. Chen for receiving the NSF Boosting Research Ideas for Transformative and Equitable Advances in Engineering (BRITE) fellow award. This award was given for the project under the title AI-Enabled Discovery and Design of Programmable Material Systems. The overall vision of the project is to develop methods to design the materials, architectures, and stimuli of programmable material systems simultaneously and predictably. Programmable materials are very promising for use in medicine, transportation, construction, and other areas as they take on new shapes or functions in response to their environments.

IDEAL Attends IDETC 2022 & IDEAL Dinner

We attended the International Design Engineering Technical Conferences (IDETC) 2022 in St. Louis Union Station Hotel, St. Louis, Missouri. The conference was held between August 14-17, 2022. In total, IDEAL members presented 4 papers which are shown below. In addition to reciving the “Paper of Distinction” recognition, Doksoo’s paper also recieved the “DAC Best Paper” award.

Prof. Chen organized a Special Session under the topic “A Dialog on Diversity, Equity, and Inclusion in Scholarly Publications” which aimed to promote the ethical practices for publishing that support diversity, equity, and inclusion (DEI) in the full community of journal stakeholders, such as authors, reviewers, associate editors, editors, and publisher.

We also had an “IDEAL Dinner” where current IDEAL members, IDEAL alumni and their associates gathered together to celebrate IDEAL, relive favorite IDEAL memories, network and have a good time!
