My professional experience is as follows:

• Sr. R&D Engineer at Pulmonx (January 2022 -- now), who is the maker of the Zephyr Endobronchial Valve that offers bronchoscopic lung volume reduction without surgery and its associated risks for patients with emphysema.

• Staff Product Design Engineer at Eargo (March 2021 -- December 2021), who developed the first and only virtually invisible, rechargeable, completely-in-canal hearing aid.

• Product Engineer at BioQ Pharma (September 2019 -- March 2021), where ready-to-use delivery systems for hard-to-prepare and hard-to-administer infusible drugs are designed.

• Sr., then Staff Mechanical Engineer at Earlens (January 2018 -- September 2019), who developed the first hearing device that uses light to transmit sound.

• Mechanical Engineer at GN ReSound (August 2013 -- December 2017), one of the World’s largest providers of hearing aids and diagnostic audiological instrumentation.

• R&D Engineer at PicoLife Technologies, LLC (January 2012 -- August 2013), a Chicago-based company excelling in the fields of electronic control, bioengineering, and medical devices.

• 2 years 1/2 of Teaching Assistantship at the University of Illinois at Chicago (2007-2009). Instructed CAD labs for 3 semesters to groups of 25 students.

• 4 years 1/2 of Research while earning my Ph.D degree at the University of Illinois at Chicago. Title: "Micro Fracture in Human Haversian Cortical Bone Under Compression". Ph.D obtained at UIC (Chicago, IL, 2011).

• A 6-month Master's thesis internship at the University of Illinois at Chicago. Title: "Multiscale Modeling of Bovine and Human Cortical Bone". M.Sc. obtained from the Ecole Centrale de Nantes (Nantes, France, 2006).

• 2 internships in an industrial environment: - A one-month internship at Anelec (Nevers, France, 2004) involving the inventory management of wire spools and electrical components, as well as the electrical control of induction coils; - A four-month internship at Imphy Alloys / ArcelorMittal (Imphy, France, 2005) during which I experimentally and numerically identified the rheological response of an alloy and studied the microscopic oxidation damage of the alloy using light microscopy.
