Q: When did you first find that your career path focused on nanotechnology?
Lee: When I visited Univ. Texas at Dallas (UTD) in 2002 as a visiting researcher, I joined a team working on carbon nanotube (CNT) synthesis and applications. In that team, I worked on fabrication of CNT-based electronic devices.   

Q: What current nanotechnology applications are you working on?  
Nanoscale transistors, Biosensors, phase change memory, electromechanical systems. All these devices can be used as a component in IT(information technology)/BT(biotechnology) systems.    

Q: What's the most rewarding thing about working with nanotechnology?
It is a chance to get an insight into nature.    

Q: Is there an example you can provide that shows how something you've worked on has positively impacted the world?
Our group has fabricated nanoscale electronic devices which will be commercialized in the near future for a next-generation IT systems. For example, those IT systems can be utilized for sensing biosignals as an embedded in wearable form.    

Q: What do you think is the single greatest impact nanotechnology has had on the world thus far?  
It makes mankind understand nature further through investigating and expanding knowledge on the 'nano-world.'    

Q: Please give an example of what you envision nanotechnology applications leading to in the future.  
Biosensors, advanced memory devices, advanced electronic devices. These devices should be very compact, low cost, have a low power consumption, and be lightweight. Nanotechnology can meet those requirements.    

Q: Do you find yourself working more in a team situation, or more alone?
I work more as a part of a team.    

Q: If you work more as a team, what are some of the other areas of expertise of your team members?   
Physicists, biologists, chemists, and (electrical/material based) engineers.    

Q: Did your university training help you in your nanotechnology work?
Yes. In my research projects, advanced characterization and fabrication tools are very crucial. My university (that is, POSTECH) has provided those very good facilities.   

Q: Do you have a mentor?  Did you in your college years?
No, I did not. 

Q: If you had to do it all over again, would you still focus on nanotechnology applications?
Yes, because I has been happy with the work and am sure that nanotechnology will bring more benefits to society.  

Q: If a high school or college student was interested in nanotechnology, what advice would you give them to help prepare take on those roles?  
Expand your studies in physics, chemistry, and biology, and get experience working with others.
