Current Status

I am currently working as the Group Leader for the Grid Development group where I architect middleware solutions, write grants, and supervise a group of middleware developers. Due to personal reasons, I am looking to relocate to the New York City area and work in business development or as a technical architect where I can leverage my knowledge and skills in emerging technologies towards business or science.

A text version of this document is available here and a pdf version is here.

I am a US Citizen.

Skills

  • Technical

    • My technical focus is on building large-scale distributed systems, from designing protocols for lightweight fault tolerance, to building peer-to-peer desktop grids, to architecting the systems-level components for several large national-scale Grid systems. I am comfortable developing for windows or linux and experienced with both clusters and middleware. I am an experienced developer in C/C++, Java, CORBA, Web/Grid Services, Tcl/Tk. My favorite language is Scheme and C.

  • Communication

    • I collaborate with scientists in a number of domains, working with them to determine the system requirements and to ensure the various solutions meet their ongoing needs. The primary domains currently include Geosciences, Computational Chemistry and Biomedical Science. In the past, I have worked closely with sales and business development to provide technical support for the life sciences and financial services. I give technical talks at various conferences, lead standards bodies in developing standards, and work with senior management to define priorities and technical direction.

  • Management

    • In my current role, I have 10 direct reports whom I manage on a day-to-day basis providing technical direction, ensuring and securing funding, working with senior management, and resolving problems as needed.

  • July 2000-Dec 2002, Senior Engineer, Advanced Technology Group, Entropia, Inc, San Diego, CA

    • Responsibilities include both internal-facing and external-facing duties, including developing and maintaining medium- to long-range technology roadmap, advanced prototype development, technology assessment, engineering design, representing Entropia at standards bodies and technical conferences, and providing technical pre- and post-sales support.

  • Summer 1998, Summer Intern, Hughes Research Laboratory, Malibu, CA

    • Worked with the Networking and Multimedia Computing group on developing an infrastructure for ubiquitous computing.

  • Summer 1995, Summer Intern, ICS Group, Lawrence Berkeley National Laboratory, Berkeley, CA

    • Developed a distributed, ultra-high bandwidth file storage system for a gigabit networking testbed.

  • Feb-Sept 1993, Scientific Programmer, Human Genome Laboratory, Lawrence Berkeley National Laboratory, Berkeley, CA

    • Developed statistical algorithms and implementations for DNA sequence analysis.
