<span class="section_header">Self (2018 - current)</span>
After a few productive years working at companies, I decided to try something different and work for myself. I'm available for hire through my consulting business, <a href="https://vonkconsulting.com">Vonk</a>. In my free time I work on personal projects and enjoy the Central Oregon outdoors.
<span class="section_header">Apple (2016 - 2018)</span>
I worked at Apple for about two and a half years, performing a number of roles and leaving as a Senior Sensor System Architect.
<br><br>
Summary:
<br>
- Technical lead for new sensor and actuator architectures (ICT4) <br>
- Engineering manager for the 3D Touch EE architecture team on iPhone X (EM1, EM2) <br>
- Transitioned from on-site manager to remote individual contributor (ICT5) <br>
- Proposed and developed new technologies for future products <br>
- Consulted with sensor/actuator teams throughout Apple to solve critical problems <br>
- Misc: hiring, mentoring, software infrastructure, docs, factory bringup <br>
<span class="section_header">SiTime (2012 - 2016)</span>
After graduating from school, I worked at SiTime for nearly four years, leaving as a Principal MEMS Development Engineer.
<br><br>
Summary:
<br>
- Technical lead for MEMS resonator design/characterization and in-house design software tools <br>
- Managed a team of three remote engineers in MEMS design and software development <br>
- Trained and mentored all seven subsequent MEMS hires <br>
- Worked cross-functionally with circuits, systems and test groups (ASIC architecture, DFT, FA) <br>
- Invented new core technologies and spearheaded their development <br>
<span class="section_header">Graduate school (2006 - 2012)</span>
I was a PhD student in the <a href='http://microsystems.stanford.edu'>Stanford Microsystems</a> lab where I developed scientific instruments for the study of touch and hearing. These problems are challenging because our bodies are very good sensors - far better than most of the tools that we use to probe them. For example, the auditory hair cells in our ears can sense pN-scale forces, roughly the force required to break a hydrogen bond.
<br><br>
The main focus of my research was designing and fabricating a better tool for studying the mechanics and kinetics of mammalian hair cells. Key performance requirements included a spring constant of 1 pN/nm, a resonant frequency of up to 200 kHz with similar actuation bandwidth, pN-scale integrated force noise, and compatibility with operation in saline.
<br><br>
Towards this goal I developed new methods for the design and modeling of piezoresistive cantilevers. Next, I integrated the sensors with novel on-chip piezoelectric or thermal actuators, and fabricated the devices in the <a href="https://snf.stanford.edu/">SNF</a>. I designed both the device layout and readout circuitry to allow for simultaneous actuation and sensing with minimal crosstalk. The final result was a family of force probes with all performance metrics 10-20x better than all work to date.
<br><br>
Details of the thermal, mechanical and electrical design of the force probes can be found in my publications and thesis. You can find slides from the majority of my academic presentations <a href="https://github.com/jcdoll/jcdoll.github.io/tree/master/papers">here</a>.
<br><br>
While at Stanford I also wrote a book with my advisor, <a href="http://www.amazon.com/Piezoresistor-Design-Applications-Microsystems-Nanosystems/dp/1461485169">Piezoresistor Design and Applications</a>. It was published by Springer in 2013 and covers everything from fabrication process options to numerical design optimization methods.
