Dmitrii Ustiugov

I am an Assistant Professor at Nanyang Technological University (NTU) Singapore. My work spans the domains of computer systems and architecture with a focus on designing fast, scalable, and resource-efficient cloud systems. My current research projects target cloud and serverless architectures, and system support for Machine Learning.

I am leading the vHive open-source ecosystem for serverless experimentation and innovation across the deep distributed HW/SW stack used in 30+ academic and 8+ industry organisations.

Bio: I received a PhD degree in Computer Science from the University of Edinburgh where was co-advised by Profs. Boris Grot and Edouard Bugnion (EPFL). Previously, I was a Postdoctoral Researcher at ETH Zurich with Prof. Ana Klimovic.

HIRING: I am looking for motivated PhD students, Research Assistants/Associates, and Fellows (aka Postdocs)!

Interested in Cloud Systems Research?

Open Positions: PhD students (August 2024 intake), Research Associate/Assistants, and a Research Fellow (aka Postdoc)
Do you love prototyping and hacking systems? Wonder what is under the hood of a modern cloud? Or just curious what the future of computing holds? I have a number of fully-funded PhD student positions for research in cloud/serverless/edge computing and systems for machine learning.

A strong applicant must have a MSc or BSc degree in computer science, electrical or computer engineering with a solid GPA. Background in programming, and systems programming in particular, as well as understanding of operating systems, networking, and/or computer architecture are key. Experience in research or working with open-source projects are desirable.

Why Join NTU Singapore?
NTU is a top international university ranked #11 in Computer Science, #26 overall in QS rankings. Singapore is an excellent place for research, comfortable and safe environment for daily life, and a melting pot of the western and eastern cultures. Also, it is in top-10 photogenic universities world-wide!

Interested? Please send me an email attaching your CV. Prospective students should also send me the transcripts (including BSc), motivation letter, as well as TOEFL (or IELTS) and GRE certificates. If you miss any documents (e.g., TOEFL, GRE) at the moment of contacting me, please elaborate on your plans to obtain them. Note, all these documents are mandatory, no exceptions are possible.

Research Directions

There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination.
Denis Diderot, On the Interpretation of Nature


Cloud & Serverless

vHive Serverless Ecosystem 

Join the vHive Open-Source Community

vHive is a full-stack open-source framework & ecosystem for serverless experimentation and innovation. vHive is representative of real serverless clouds, as recognized by leading serverless providers and an ASPLOS'21 Distinguished Artifact Award, integrating production-grade components, including AWS FirecrackerContainerd and Kubernetes.

Today, vHive is in use in 30+ top universities around the globe, for both research and teaching, supported and/or sponsored by 8 international IT companies.

vHive tutorials featured at SOSP'23 (slides) and ASPLOS'22 (YouTube).
