Biography

Prof. G. Logan Liu has a multidisciplinary educational background and was trained in both engineering technology development and clinical medical research environment.  He obtained his joint Ph.D. degree in Bioengineering from University of California-Berkeley and University of California-San Francisco with the honor of outstanding publication award.  His graduate research was focusing on developing micro and nanophotonic and electronic molecular detection systems for cancer diagnosis and therapy. He received his postdoctoral training in Helen Diller Family Comprehensive Cancer Center at San Francisco where he worked with breast and prostate oncologists and clinical medical workers to apply novel nanotechnologies in diagnosing and curing cancers.  After the medical postdoctoral training, he joined Lawrence Livermore National Laboratory as a prestigious Lawrence Fellow funded by U.S. Department of Energy to foster the nanobiotechnology research there for biodefense applications. In 2008 Prof. Liu joined University of Illinois at Urbana-Champaign as an assistant professor in department of electrical and computer engineering and micro and nanotechnology laboratory. His expertise includes design, modeling, and fabrication of nanoelectronic and nanophotonic devices and their biomedical applications. His current research interest is developing “Nanobionics” by integrating solid-state optoelectronic nanodevices with functional biomolecules and studying the properties of electrons, photons and ions in the hybrid system.  In his vision, varies of nanobionics systems will be created for applications in health care, energy harvesting and environment protections.

Teaching Statement

Teaching Philosophy - Being engaging, inspiring and innovative In my view, teaching in higher education institutions is not only to transfer advanced knowledge to students, but more importantly to inspire younger generations to use the learnt knowledge pursuing their own career goals and serving the whole society better in the future. Particularly for the undergraduate and graduate students in my department of electrical and computer engineering at Illinois, someday many of them will become the pillars and leaders of electronics and information industry in the United States and many other countries all over the world. Training them to be highly qualified and motivated electrical and computer engineers is a huge responsibility for every faculty member in my department including myself.

Always striving to continuously improve my teaching effectiveness, I also realize my teaching should be a constantly refreshing and reforming task. Our students from the younger generation in 21st century are facing unprecedented societal and psychological challenges, such as being overwhelmed by rapidly evolving electronics and information technologies, being used to learning from internet and social networks, as well as having huge pressure from the fierce global competitions in the economic recession with uncertain job markets. In light of these emerging challenges, the current generation of students may not respond to the traditional classroom teaching methods as effectively as 10-15 years ago when I was in their positions. As an educator I believe it is my obligation to help our young students overcome these challenges and concentrate on course materials to learn as much as they can. I also believe it is an opportunity for us to be innovative in improving teaching methods by taking the advantage of modern information technologies for the benefit of optimizing the learning efficiency of our young students.

For highly-challenging required courses such as ECE 440, in which many students showed limited interests to classical device physics, I have been gradually modifying my teaching strategy and methods to motivate students to a higher level and help them connect the relevance of fundamental physics to contemporary technology innovations. Although improving the teaching effectiveness of historically difficult course still needs consistent solid endeavors for a long time, I will keep working hard toward this objective. I firmly believe we should and can educate our students better. In addition, I am designing a new course in order to inspire our young ECE students to be creative and innovative and to help them prepare for the emerging industrial opportunities in health care technology revolutions.

Research Statement

My research area lies at the intersection of engineering, physics, chemistry, biology and information technology including both theoretical and experimental aspects. Particularly I have been extremely interested in studying the micro and nano scale interface between solid-state electronic/photonic system and biological system. My research efforts have been dedicated to understand and control molecular and cellular systems using nanoengineering methods for the benefit of curing diseases, and improving life quality and preserving environmental sustainability.

Being aware of the grand challenges of 21st century we are facing in the United States and the whole world such as cancer diagnostics and therapy, agricultural and water sustainability, and affordable health care for more people, I worked tirelessly to foster innovative research projects in my lab to directly respond to these challenges with the immediate and long-term scientific, technology and societal impacts. The three closely related thrusts of my research are 1) Nano-Bio hybrid photonic devices, 2) Green microfluidic environmental sensors, and 3) Mobile digital health biochips. Due to the unique nature of my research in ECE department, I have been very active in reaching out to many Illinois colleagues from different disciplines including chemistry, physics, environmental science, agricultural and food engineering, molecular and cell biology. By participating in many campus-wide research alliances, I have contributed to a few center-scale federal grant applications and my research group has created many novel works through the multidisciplinary collaborations.
