  Voltage Clamping Circuits with High Current Capability, developed at IBM in 1985 while working on a 4Mbit DRAM
US Patent: #4,958,093
European Patent: #90107764.4-
Cadence Design Systems, Inc. (Allentown, PA)
September 1998 - present
Developed the Affirma Model Compiler, which takes a high-level description of a circuit element, produces the C/C++ code needed to model the eloement, then compiles the code into a circuit simulator.
Developed the Affirma Model Writer, a point-and-click interface which guides the user through the process of creating Verilog-A circuit models.
Distinguished Member of Technical Staff
Bell Labs Innovations for Lucent Technologies (Allentown, PA)
January 1992 - September 1998
Created [incr Tcl], an object-oriented flavor of the Tcl programming language. [incr Tcl] has been used by thousands of developers worldwide, at companies in telecommunications, aerospace, finance, and many other fields.
Used Tcl/Tk and [incr Tcl] to develop graphical user interfaces for dozens of tools, including a quantum transport simulator, drift-diffusion simulator, and 2-D and 3-D interconnect capacitance simulators.
Developed a database-backed Web site for advertising training courses, along with an automated registration system for handling enrollment.
Developed an object-oriented framework (~30,000 lines C++) for exchanging information between semiconductor process and device simulators.
Developed a training business for Tcl/Tk and [incr Tcl] that grossed roughly $500,000 per year for 4 years. Developed more than 500 pages of training materials and dozens of lab assignments for 7 days of training. Taught this series several dozen times within Bell Labs and at many other companies.
Moravian College (Bethlehem, PA)
Spring 1994
Developed and taught an introductory programming course using the Turing language, which is similar to Pascal.
Senior CAD Engineer
Dawn Technologies, Inc. (Sunnyvale, CA)
September 1990 - January 1992
Developed an interpreted, C-like scripting language (Sim-C) used as the core of a framework for device simulation.
Developed a full-featured, 2-D/3-D graphics package (Sim-C graphics) for plotting and visualization of scientific data.
Research Assistant (PhD/MSEE)
Solid State Device Simulation Area, Purdue University
May 1987 - September 1990
Developed Fortran 77 programs (SEQUAL/QUEST) which simulated quantum physics of electron transport in ultrasmall devices.
Developed SunView applications for plotting simulation results.
Integrated Circuit Designer
International Business Machines Corp. (Burlington, VT)
Summer 1985
Invented a novel voltage-clamping circuit used to maintain a preset voltage on the bit-lines of a 4 Mbit dynamic RAM. The circuit was patented because of its high efficiency and compact size.
