About Panos

Panos, an Official Member of Engineering New Zealand, is interested in various aspects of Software Engineering but in particular, Self-Adaptation in Clouds, Language Runtimes and Embedded Systems, focusing on the Testing and Satisfaction of Nonfunctional Requirements as well as Systems' Security. He joined the the University of Waikato in July 2018; soon after, he started the Oceania Researchers in Cloud and Adaptive-systems (ORCA) lab. Additionally, he is serving as an Adjunct Professor in the Faculty of Computer Science at the University of New Brunswick in Canada.

Panos is a key researcher in the $12.5M Ahuora project 2020-2026. Ahuora aims to decarbonize the process heat sector of New Zealand, via Adaptive Digital Twin technology. The project comprises a sizable Software component: we'll be needing many Software Engineers over the following years. Take NCEA Calculus Level 3 and study Software Engineering!

Panos received his Bachelors in Informatics and Telecommunications from the University of Athens in 2010. He worked for four years as a Software Engineer, Consultant and Academic Tutor before moving to Canada and the University of New Brunswick for graduate school. He completed his Master's in Computer Science in 2014 and his PhD in 2018, both as a member of the IBM/UNB Centre of Advanced Studies - Atlantic. While in Canada, he taught CS courses (after completing a Diploma in University Teaching in 2014) and participated in industrial R&D projects.

For his BSc thesis, Panos constructed a converter of Conjunctive Grammars (Context-Free plus Intersection) to their respective automata and vice-versa. For his master's thesis, he enhanced the IBM J9 JVM with a tool that measured thread-park contention in the Java Util Concurrent library. For his PhD thesis, he explored numerous performance, modelling and resource allocation issues in the intersection of platform clouds and language runtimes, in a work that also resulted into two patents and four defensive anti-patent disclosures. He is also a member of the Verilog-To-Routing FPGA CAD tool open source community, where he contributes and conducts research related to improved synthesis of circuits for embedded systems.

About ORCA

The Oceania Researchers in Cloud and Adaptive-systems (ORCA) [also known as Ohu Rangahau Kapua Aunoa in Te Reo Māori] lab was founded in January 2019. Its mission is to facilitate excellent research in the fields of Self-Adaptive and Self-Organizing software systems focusing on Cloud, Language Runtime and Embedded Systems.

Self-Adaptive Software is an exciting new field merging ideas from traditional Software Engineering and Computer Systems, with Artificial Intelligence (AI), Machine Learning (ML), Control Theory, Data-Driven Control, Game Theory, etc. Its goal is to enable applications to satisfy dynamically changing requirements in a dynamically changing environment.

The ORCA lab comprises multiple Waikato research students and involves Waikato, New Zealand and International Academics. It maintains active international collaborations with researchers from the UNB/IBM Centre of Advance Studies-Atlantic at the University of New Brunswick, Canada; the Chair of Computer Architecture and Parallel Systems at the Technical University of Munich, Germany; and ASRC Federal in the United States.

To date, the ORCA lab has contributed in the following funded projects:

• STRATUS
• Huri Whakatau
• Optimizing Node.js for the Cloud (IBM, Red Hat and UNB Canada)
• Self-learning EBike (Nerra Drive Systems & Callaghan)
• Ahuora

Perspective Students

I am always on the lookout for star research students with strong mathematical and computer/software systems skills. Academic publications and/or relevant industrial expertise will be highly appreciated. The University of Waikato offers competitive PhD and Master's Scholarship to the best applicants; contact me if you think you are a fit!

I occasionally take in strong undergraduate interns; however, I cannot provide any relevant funding.

Interested High School Students

So, you want a career in Software Engineering? Great choice! Ensure you complete Level 3 Calculus! I recommend you score Excellent or Merit in the following NZ NCEA subjects:

It'd be great, however, to also gain a broader comprehensive knowledge. Remember that Engineering is for the people and you need to be able to empathize and discover problems. Consider earning at least a Merit in the following NZ NCEA subjects:
