(Oct 2017) Best paper award at CASES 2017.

We have won another best paper award (5th paper award in under 2 years!).

This one is for the joint work with Prof. Gupta and his students on new methods (including novel context-dependent ECC methods) for low-cost IoT devices. The paper titled “Low cost memory fault tolerance for IoT devices,” and is authored by Mark Gottscho, Irina Alam, Clayton Schoeny, Lara Dolecek, and Puneet Gupta.

(June 2017) Multiple awards and honors for LORIS students: Fred, Clayton & Ahmed.

  1. Clayton Schoeny and Ahmed Hareedy are both selected as the recipients of the prestigious UCLA Dissertation Year Fellowship.
  2. Ahmed Hareedy is selected to receive Excellence in Teaching Award from the EE Department for outstanding performance as a TA. This highly competitive award is given annually to only a single course TA in the department.
  3. Fred Sala will augment his best dissertation award with another honor: Fred is selected as one of only two marshals for the campus wide UCLA Doctoral Ceremony. This honor is bestowed upon students with truly outstanding academic records.

New journal paper on sequence reconstruction from insertion-induced traces

New journal paper by F. Sala, R. Gabrys, C. Schoeny, and L. Dolecek, and titled “Exact Reconstruction from Insertions in Synchronization Codes,” will appear in IEEE Transactions on Information Theory. The paper offers a closed form solution on the number of insertion-induced traces needed for exact codeword reconstruction, for codewords of  synchronization code. Proof heavily relies on combinatorial arguments. The results have applications in domains that study sequence reconstruction from “difficult” channels such as insertions and deletions, as encountered in e.g., phylogenomics.

Post-doc positions available!

2 postdoc positions available in Prof. Lara Dolecek’s research group at UCLA, starting this fall. We are looking for talented students who want to work on one of the following:

1. Coding theoretic methods and algorithms for emerging memories and modern computing systems

2. New algorithms and coding-theoretic techniques for data management (data science)

Both projects are interdisciplinary. Postdocs will be working closely with Prof. Dolecek and a vibrant group of graduate students, and will have the opportunity to collaborate with other researchers and to interact with our industry sponsors.

Strong background in mathematics and interest in interdisciplinary research are required.

Prospective students should contact us via email at


with subject line

[Prospective postdoc interested in LORIS research]

along with their CV and 3 selected publications. Students should plan to arrange for 2 letters of recommendation to be sent to the email address above.

5 new journal papers are published

LORIS group recently published 5 new journal articles, on topics ranging from efficient file synchronization (Sala, Schoeny, Bitouze, Dolecek, TCOM, June 2016), to LDPC codes for multi-level Flash and modern HDDs (Hareedy, Lanka, Dolecek, JSAC, Sept. 2016) and (Hareedy, Amiri, Galbraith, Dolecek, TCOM, Aug. 2016), and to spatially coupled codes (Amiri, Reisizadeh, Esfahanizadeh, Kliewer, Dolecek, TCOM, Sept. 2016) and (Esfahanizadeh, Hareedy, Dolecek, TMAG, Jan. 2017).
