Reference excerpt

Zachary John Lemnios (born February 21, 1955) is an American scientist, executive, and engineer who has worked in government, industry, and academia. Most notably, he held the post of Assistant Secretary of Defense for Research and Engineering (currently known as Under Secretary of Defense for Research and Engineering) from 2009 to 2012, and he has served as the first Chief Technology Officer of MIT Lincoln Laboratory, and as Vice President of Research at IBM. Lemnios later founded ZJL Consulting, LLC.

Early life Zachary Lemnios was born on February 21, 1955, in Cambridge, Massachusetts, and he was raised in Lexington, Massachusetts. He attended the Lexington public schools and graduated from Lexington High School. He was an avid amateur radio operator (WA1LTA) and enjoyed building electronic projects.

Education Lemnios received his Bachelor of Science in Electrical Engineering (BSEE) from the University of Michigan in 1976 and his Master of Science in Electrical Engineering (MSEE) from the McKelvey School of Engineering at Washington University in St. Louis in 1979. His thesis was titled, "The Fabrication and Evaluation of Microwave Field Effect Transistors". He also completed post graduate courses, including the Harvard Kennedy School of Government Program for Senior Executives in National and International Security (NIS).

Career Lemnios held technical and leadership positions across industry at Hughes Aircraft, Westinghouse Electric, and Ford Microelectronics that led to the development of advanced microelectronic components. Lemnios served as the first Chief Technology Officer of MIT Lincoln Laboratory. He joined the Information Processing Technology Office (IPTO) in April 2002, and was influential in the creation of the Personalized Assistant that Learns program. Lemnios has served as chair and on the Technical Program Committee of GOMACTech and GaAs IC Symposium.

Lemnios was confirmed as Assistant Secretary of Defense for Research and Engineering by the Senate on June 19, 2009, and he was sworn in on July 2, 2009. In this position, Lemnios was the Chief Technology Officer for Department of Defense. Lemnios established the DoD Science and Technology Executive Committee. Lemnios served as a Principal member, Committee on Technology of the National Science and Technology Council; Advisor, Defense Acquisition Board; Chairman, Radiation Hardened Oversight Council (RHOC); Chairman, Defense Science and Technology Advisory Group (DSTAG); Chairman, Armed Services Biomedical Research Evaluation and Management Committee; Chairman, DoD Combat Feeding Research and Engineering Board (CFREB); and chairman, DoD Biometrics Executive Committee. He launched four imperatives for the Defense Science & Technology enterprise, which set the framework for how the Department of Defense prepares for future US national security needs:

"Accelerate the delivery of technical capabilities to win the current fight and develop the skills and processes to rapidly field capabilities in any future fight". "Prepare for an uncertain future" by investing in key technologies such as cyber science and technology, electronic warfare and protection, data-to-decisions (to reduce cycle time and manpower for analysis), engineered resilient systems (for protection against infiltration and to develop agile manufacturing for trusted defense systems), countering WMDs, autonomous systems, and enhancing human systems (human-machine interfaces). "Reduce the cost, acquisition time, and risk of major defense acquisition programs". "Develop world class science, technology, engineering, and math capabilities for the DoD and the Nation". Lemnios announced his resignation on November 20, 2012. He left the Pentagon and joined IBM where he served as Vice President for research strategy.

Awards Lemnios has authored more than 40 papers and holds 4 patents in advanced Gallium arsenide device and MMIC technology. Lemnios is a Life Fellow of the Institute of Electrical and Electronics Engineers. In 2018, Lemnios received the University of Michigan Electrical and Computer Engineering Alumni Impact Award for "helping to shape the new Frontier in Electrical Engineering and Computer Science", the highest recognition granted by ECE to its alumni. Lemnios received the Washington University in St. Louis Alumni Achievement Award.

Personal life He was selected by the Department of Defense to be one of the USA Science and Engineering Festival's Nifty Fifty Speakers to speak about his work and career to middle and high school students in October 2010. Lemnios was a special guest at the Team America Rocketry Challenge in 2010, delivered remarks to young students at the Real World Design Challenge in 2012, and was a special guest at the FIRST Robotics Competition in 2012.

Worked examples

Example 1 — a first encounter with Zachary J. Lemnios

Start with the simplest possible case. Write down what Zachary J. Lemnios claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Zachary J. Lemnios before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Zachary J. Lemnios ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Zachary J. Lemnios

In research: Zachary J. Lemnios appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Zachary J. Lemnios in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Zachary J. Lemnios is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, American people of Greek descent, American scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Zachary J. Lemnios outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
