About me

Since 1 Aug 2016, I am a Research Associate within the Digital Technology Group, working on optimising provenance systems with the goal of dealing with large quantities of data, as produced by low-level tracing systems. Within the CADETS project, such tracing systems (like DTrace) are used for detecting Advanced Persistent Threats (APTs). I also contribute to work being done on developing Distributed DTrace and to the development of new versioning models for provenance.

I have submitted my PhD thesis, entitled "Provenance-based computing" on 20 Aug 2016 and have passed my examinations (viva) on 5 July 2016. I am in the process of finalising the corrections required for submitting the final version of the thesis. [draft pdf version available on request]

I have started my PhD in the University of Cambridge Computer Laboratory in October 2011, as a member of the Digital Technology Group. My supervisor was Professor Andy Hopper and I have worked closely with Dr. Ripduman Sohan in exploring the research area of provenance, looking at building systems for tracking the history and inter-dependencies of pieces of data as they are produced or consumed in arbitrary computational workflows.

My PhD research was funded by UK's EPSRC, by a CHESS Scholarship, and by a Computer Laboratory Departamental Scholarship.

I am a member of Wolfson College.


My research interests span the following topics: The overarching goal of those research interests is the understanding and automated control of complex systems and of their performance during unexpected situations (such as chain failures).


I supervise or have supervised for the following courses:


I have previously been an intern at both Microsoft (2010) and Google (2013), where I have worked in infrastructure teams dealing with performance evaluation and service configuration, respectively. My time within both companies has helped me gain valuable experience and a better understanding of real-world requirements at scale. This continues to drive my interests towards research that has a real impact and solves challenging engineering problems.

I have graduated (B.Eng.) as valedictorian from the "Gh. Asachi" Technical University of Iasi, Romania. My bachelor thesis dealed with real-time object recognition in video streams using interest point detectors. I have obtained a M.Sc. in Distributed Systems from the same university, with a research stint in the Institute of Computer Graphics and Algorithms from the Vienna University of Technology, during an ERASMUS Scholarship.

GPG Keys

If you want to securely communicate with me or make sure a particular software artifact was released (signed) by me, please download my OpenPGP public key 0x1AFE0D9B85AA6C3E from one of the public key servers or from this key file (https, local copy).

After importing the key into your keyring, please verify that its fingerprint matches BC97 80C1 939D 3711 6415 A117 1AFE 0D9B 85AA 6C3E (please take this value as a hint, and only when you have accessed this page through https). The usual way of checking the fingerprint is through out-of-band communication (phone, email, discussion in person).

I use different subkeys for encryption/authentication/signatures (given below with their ids). Unless compromised, the validity date of most of those subkeys will be prolongued before they expire. An exception is the encryption subkey, which I might choose to rotate in order to limit the number of communication sessions that are leaked if the corresponding private key is compromised.
