 It's my great pleasure today to introduce Dr. Chi-Wan Lee. He's the Leslie A. Gettys professor of biomedical engineering at, in the Weldon School of Biomedical Engineering, as Arvin just pointed out, and I've gotten to know Chi-Wan as a colleague over the years, and he is just on a tremendous trajectory in doing real work that impacts human lives in clinical settings. So he's also a professor in mechanical engineering and courtesy through materials engineering here at Purdue. You guys, MS and PhD degrees in mechanical engineering from Stanford University with Professor Xiaoling Zheng in 2009 and 2013, respectively. Prior to joining Purdue in 2015, he was a postdoctoral researcher in the Department of Material Science and Engineering at University of Illinois at Urbana-Champaign with Professor Jim Rogers, John Rogers. His scholarly efforts are dedicated to addressing unmet clinical needs using novel yet simple wearable devices and a clear path towards translation to produce measurable clinical and economic impacts. He received a number of prestigious awards, including the 2021 Sensors Young Investigator Award, the 2020 College of Engineering Early Career Research Award, 2019 NIH Trailblazer Award, and the 2019 Korean American Scientists and Engineering Association Young Investigator Award. He's published over 60 papers, four book chapters, four patents in the US, 11 utility patents, 12 provisional, launched three startup companies, recently got an RL1 grant with colleagues looking at, what's the technology? It's drug eluding contact lenses and more on the way, hopefully. Fingers crossed. It's my great pleasure to introduce Chi-Wan Lee, and thank you for coming and listening to his presentation. First of all, I'd like to thank the College of Engineering for giving me this opportunity to celebrate my promotion. So I've been actually thinking about what to say today throughout the Thanksgiving holiday, and I decided to spend my 10 minutes to thank all of you who have been extremely supportive to my, you know, first step to little success at Purdue University over the years. Looking back to the the past 60 years at Purdue, I think it has been quite challenging time, especially through an ongoing pandemic, and then many times I feel like I'm trapped in the infinite loop to keep generating grant proposal, journal publication, you know, service, teaching, mentoring, again and again, again, infinitely. That's not an easy job, I think, and especially I found that dealing with Libya number two is the most stressful job over the year. So without your great support and help, I don't think I could get through this difficult time. So today, I'd like to thank all of you. That is my my celebration. First of all, I'd like to thank Purdue and the search committees who have really good eye to ping me six years ago, including Professor Ali Sakri, Tim Fisher, Pedro Irajaki. Actually, as you may notice here, actually two of them have left Purdue already. So I think it is time to do something for Ali to keep him here. Anyway, I think I truly believe that Purdue is one of the world-class top university where especially the junior faculty can be successful. I believe that Purdue provides very unique working environment. Let me give you my example. Six years ago when I was in job market, I got invited for on-site interview from eight different schools across the world. Two of them were Purdue. So at that time, I defined myself as a 100% mechanical engineer by the training and then and therefore I applied for I had never applied for any bio-related schools at that time. I only applied for mechanical engineering by the nature of my research. At that time, my research was about, you know, flexible lightweight solar cells. I called this a solar sticker so that you can attach to anywhere you want. So Professor Ali Sakri invited me for the on-site interview through mechanical engineering at the time and I gave a talk about this solar sticker and I proposed to him to use the world-class state-of-art roll-to-roll facility in the Burke Nanotechnology Center at Purdue for the potential mass production of my solar sticker. That was my proposer. And we went to Bistro 501 for dinner with Professor Tim Fisher and he brought a very brilliant idea to the table. And he talked about potential application of my solar sticker for many biomedical applications. That was quite interesting. So actually he, on the table actually, he sent a text message to Professor Pedro Irajaki, who was the search committee chair in BME at that time. And he sent me an email at the same night saying that, hey, are you interested in giving another talk in BME? And I replied back to him, hey, my research is about solar sticker, would that be okay? He said, no problem, just come. So I came back to Purdue again in the following week for another talk in BME. And then it turns out that all the meetings with the number of faculties in BME as well as other bio-related departments and schools and research centers went really productive. So it was a really exciting opportunity. So I feel like Purdue has no barrier between the labs, the schools, you know, centers, and so on and so on. And I think that I could work with such a world class, you know, top class colleagues and students regardless of their department or schools, whatever affiliations. So that was actually a very unique opportunity for Purdue. Actually, none of other universities had made such an attractive offer with this condition. So I decided to come to Purdue. And over the time, of course, I found, I identified many good things, many other good things about Purdue. And actually, these are the several keywords that I have used whenever I serve as a search committee members to convince them to come to Purdue. And I always emphasize that we're moving toward this stress-free working environment. In the next slide, I'd like to thank my mentors, role models, and readers. Actually, there are many beautiful pictures over there you're missing now. And I really appreciate all of their great support throughout the year. I'm really always feeling like I'm a lucky guy to have them. Page number three, have these guys as my mentor, the next page, actually, this one. Yeah, here you go. Here's my mentors, leaders, and role models. I really appreciate their great support. Yeah, what's really impressive thing is that they never say no for whatever I ask. They always say yes. That's the one of my key success factor. As soon as I joined Purdue University, six years ago, I leached out to purpose keen on part in BME, who is one of the most successful faculty in nearly every aspect, including research, teaching, mentoring, and entrepreneurship. So he very naturally become one of my role models. So I knocked his door and asked about his secret source to the success. And he emphasized me, this is the following three key success factors. The first is whiskey and golf. And then he always said that what would be the point of your life if you don't know how to enjoy whiskey and golf? Just enjoy your life first. That's the first wisdom from him. And then he emphasized this real-world impact, real-world impact. He always said, Chi Hwan, you better better understand about the clinical need in the BME field. You need to meet clinical mentor, the doctors, medical doctors, nurses, caregivers, patients, better understand what they need. They know the problem. And as an engineer, you know the solution or you can figure out the solution. So it turns out that actually, Kinamo is very light. So I always take this wise mentor device very seriously. So I took my first and second year at Purdue to give a volunteer giving a seminar in many, many non-engineering department, including IU medicine, optometry, Michigan medicine, Purdue Vasco, pharmacy, speech-language-sharing sciences. And throughout the courses, I could be able to form very interdisciplinary Avengers teams with a number of such a world top-class researchers and scientists. I'm always feeling blessed to work with them and I'm so proud of being a part of these Avengers teams. And we have secured a total of $27 million over the past six years from multiple funding agencies and we keep generating joint publications together. And lastly and mostly, I'd like to thank my mentees. I think all of my group members are over there, backside. And I'm always feeling like I'm lucky guy to work with such a talented and self-motivated students and postdoc. And as you can see here again, so my group has a lot of student postdocs from different backgrounds. They are from ME, BME, MSC, IDSC, and MD, PhD, and so on and so on. So I really like this environment. So I really appreciate Purdue that allow me to do these things. And this interdisciplinary working environment worked really well and one of my, some of my first PhD students in BME and ME and my first postdoc in BME have successfully settled down to the tenure-track assistant professor at their dream schools. Even after, right after they got PhD degree from Purdue. Just two months later, they got the job offer. And I also have my first postdoc in BME who has become a senior scientist, research scientist at Samsung Advanced Institute of Technology. Surprisingly, his salary is higher than mine. So I think we got to do something to fill this gap. So thank you for your attention and I would be happy to answer any questions. Were there any particular instances as you were going from a transition into doing more clinically applied biomedical engineering that were aha moments or transitions that you remember looking back over the last six years that were really impactful? I think it took nearly three years to successfully identify the practical clinical means out there and the former, the first Avengers team to tackle the problem. And I think the most difficult time for my career was the first three years. So I gave a lot of talk in many different places, you know, non-engineering places, trusting. It is very uncomfortable experience to give a talk in front of medical doctor, session engineer. So I was very, very nervous at the beginning, but I get used to eventually and I tried to listen to their need and I tried to find a solution with my colleagues. It took three years. And then it didn't happen suddenly. It's just very naturally getting better. And then we work together to tackle the problems along the way. And I think every aspect, you know, I cannot most like, you know, if I focus on the real world impact first of all, all other things follow naturally. He always told me that you don't need to worry about tenure. You don't need to worry about number of paper impact back. No worry about it. You should care about real world impact first. All other things follow naturally. He was like, I think he was like. So, yeah, that's my story. Very natural transition. Yeah, Wayne. Expand your companies for the real world impact. Then you don't need to worry about the salary issue. You are partially like. You'll be rich. Thank you for the comment. Yeah. Do you want? What's next? What's next? Thank you for asking. Actually, I have a couple of plans. Actually, Kenan gave me three, three advice, but I have been quite busy to enjoy the first two things. So that's my, that's I need to learn how to enjoy whiskey and golf. That's my one of my part of plan. But I think that David wouldn't disagree with this my plan. So I have a near term and future goal plan. Near term goal as a low hanging fruit. I want to make the world in school within national top 10 engineering school in the near future. I'm talking about low hanging fruit. My long term goal is to make it national top five. And my personal goal actually is pretty much well aligned with what Kenan say. I really want to make a real world impact with my Avengers teams. I'm not talking about 100 years later within my lifetime. I want to make that happen. All right. Thank you very much. Thank you, everyone. One more time.
