He has published more than 25 papers, contributed to several books, and holds 22 patents.


Steve Caliguri, Vice President, Telecom

Mr. Caliguri has over 25 years of experience in the telecom and technology industries, and has led the Acorn telecom division since its inception. Previously, he was one of eight founders and senior executive officers at Leap Wireless, Inc., an international wireless telecom company with a portfolio of spectrum licenses (Mexico, Chile, Australia and Russia) that began as a 1998 spin-off of QUALCOMM. As a key member of Leap’s founding executive management team, Steve helped guide Leap’s three-year transition into a major international wireless competitor and the 10th largest U.S. carrier, with 1,000 employees, revenues exceeding$500M annualized, and more than 1 million wireless customers. In addition, Steve has extensive M&A and corporate development experience, and was responsible for Leap’s profitable investment in the Chilean wireless operating company SMARTCOM PCS. Prior to Leap Wireless, Steve was senior director of product management for the CDMA Infrastructure Division of QUALCOMM, where he focused on the development of world-class products for system-level applications including WLL, mobility systems, data systems, and advanced network solutions. He received his Bachelor of Science degree in physics from Boston College in 1984 and an MSEE from Northeastern University in 1988. He also attended Boston College’s MBA program.


Dr. Paul Clifton, Vice President, Semiconductor

Dr. Clifton has broad experience in semiconductor process and device engineering, simulation and optimization gained over more than thirty years in industrial and academic R&D. Prior to joining Acorn Technologies, he worked on performance optimization, reliability, variability and yield ramp of multiple CMOS technology nodes as a semiconductor device specialist at PDF Solutions, a Silicon Valley-based provider of advanced process-design integration solutions to the IC industry. Before PDF Solutions, he held senior application engineering roles in TCAD at Silvaco, TMA, Avant! and ISE. He has specific process engineering expertise in plasma etch, CVD, MBE, including compound semiconductors and strained silicon. Paul has also worked as research team leader at the University of Newcastle on a pioneering development program for strained Si technologies in Europe. In addition, he has wide international experience having worked at ISE AG (Zurich, Switzerland), PDF Solutions (Munich, Germany) and held research fellowships at the Universities of Southampton (UK), Tohoku (Sendai, Japan), and at the CNRS (Toulouse, France) and a lectureship in Microelectronics at the University of Durham (UK).


Dr. Andreas Goebel, Director, Semiconductor R&D

Dr. Goebel has over 20 years of industrial and academic R&D experience across material science, semiconductor physics, semiconductor processes and devices. Prior to joining Acorn Technologies in 2008, he worked on optical interconnect silicon technology combined with GaAs Quantum-Dots comb-laser development at Innolume, a premier manufacturer of ‘quantum dot’-based diode lasers and laser modules. Before Innolume, he held increasing strategic positions within the office of the president at Applied Materials, responsible for their optical interconnect development and roadmaps, along with various positions focused on next generation lithography. Until 1999, Dr. Goebel was educated at the Max-Planck Institute for Solid-State Research under Manuel Cardona, one of the founding directors and a most cited physicist, focusing his Ph.D. research on fundamental optical properties of semiconductors, their electronic band structure and electron-phonon interaction. He holds a Masters in Physics from the University of Ulm in Germany; a Master of Science from Oregon State University and a Ph.D. in fundamental semiconductor physics from the Max-Planck Institute in Germany. Goebel was awarded the Otto-Hahn Medal from the Max-Planck Society and holds over 10 patents on process technology, optical interconnect and integration, transistor technology and materials considerations. Andreas is a leading author and co-author of more than 25 peer-reviewed papers.
