The laboratory of Sumita Pennathur in the department of Mechanical  Engineering at UCSB is looking for postdoctoral candidates with expertise in silicon microfabrication, MEMS and optical systems to join an exciting new project to revolutionize  continuous glucose monitoring for Type I diabetics. 

Currently marketed continuous glucose monitors are painful to insert, must remain long-term  (one week) within the body, and suffer from poor accuracy. A one-a-day  painless patch that would continually (i.e., every 5 minutes) monitor blood glucose would solve a lot of issues of current technology. To build such a system requires a chemical glucose sensing compatible with the small sample volumes.

Therefore, for this position, we are seeking a candidate who is willing to collaborate with mechanical engineering, bioengineering, and chemistry faculty and researchers to optimize sensitivity, dynamic range, stability, size, weight and power consumption of a prototype silicon dual-junction photodetector for the non-enzymatic fluorescence-based ratiometric glucose sensor that we have developed. Once optimized, we aim to integrate the detector with a microneedle array towards the development of a wearable glucose sensor. Future goals include developing multi-species arrays for detection of other biologically relevant species and further integrating the system with CMOS-based electronics.

Postdoctoral Scholar appointments are full-time training programs of advanced academic preparation and research training under the mentorship of a faculty member.

Basic Qualifications: PhD in engineering, physics or a related discipline.

Additional Qualifications:

  1. 1 + years experience with silicon microfabrication (specifically mask layout, lithography, etching, annealing, thin film deposition, die singulation, die attach and wire bonding.
  2. 1 + years experience MEMS/microfluidics (ie. microchannel fabrication and wafer bonding), and silicon photodiode, CMOS photosensor, or solar cell experience (including design, analysis, fabrication and characterization).

Preferred Qualifications:

  1. Excellent written and verbal communication skills; solid organizational and planning skills; self-motivation; detail-orientation; and proficiency with Word, Excel, and PowerPoint.
  2. Must be able to perform statistical analysis; follow complex instructions; multitask; carefully document work in written  records; work both independently and as part of a team; plan and  troubleshoot experiments independently; and work in a fast-paced and dynamic research environment.

The initial appointment will be for one (1) year with a possible two (2) year reappointment if mutually agreeable.

Please submit a completed application to UCRecruit at by December 20th, 2018 for primary consideration.

Anticipated start date is Friday, February 1st, 2019.
