John CiraldoJohn Ciraldo, NUFAB Research Associate, Process Engineer 


What technical expertise do you offer?

NUFAB offers a broad range of technical expertise around thin film deposition including recipe and process development with control over all parameter (stoichiometry, roughness, optical properties, conductivity, grain structure, etc.). We possess decades of combined experience in both process development and film characterization of films by both CVD and PVD.


How do you facilitate research collaboration?

There are multiple approaches to research collaboration at NUFAB. Often we are presented with a ‘black box’ problem where we develop solutions that are independent of the application – we find this is desirable for our industry users. We also offer full development, where we are provided with a problem statement and a guiding parameters and develop and full solution.


What inspired you to work in this field?

I held an interest in technology and ‘how things work’ as a child, which led me to study physics and engineering in college. As I got more involved with the programs, I began to appreciate the role specific materials play in technical solutions and developed a keen interest in how to develop those materials to find solutions to complex problems.


What are the everyday practical applications of your research/work? How does what you’re doing make a difference to non-scientists?

Amongst the technologies I have worked on at NUFAB are MEMS devices for consumer electronics and medical devices – the real world need for these is high and obvious, I think to most people. The latter offers immediate life-saving value, which is, of course, very gratifying.


What’s the most interesting project or achievement that you’ve been involved in at NUANCE?

The most interesting projects to me are the ones that are challenging to achieve. Working with compounds that are complicated to synthesize and require novel approaches to deposition is quite enjoyable to me, independent of the final application.


What excites you most about the future of nanotechnology?

Right now, we are seeing an explosion in nanotech for medical applications; everything from sensors to in-vivo drug delivery. In the process, we are rewriting how medical treatments are done. This both excites and fascinates me.
