Bienvenidos to my personal web space! My name is Yasin Silva. I am an Assistant professor of Applied Computing in the School of Mathematical and Natural Sciences of the New College of Interdisciplinary Arts and Sciences at ASU. I obtained my Ph.D. and Master's degrees at Purdue University - Indiana USA. I am happily married to Lee Ann, who works as a Spanish teacher at Libery High School, and we have two wonderful little boys, Gabriel and Caden.
My current areas of research deal with similarity-aware query processing and optimization, privacy assurance in database systems, scientific database systems, and web-scale data management systems. However, I am always very interested in exploring other areas related to data management systems and security in general.
In this site you will find information about my research
and teaching work.
You will also find information about other projects that Lee Ann and
I are involved in, especially Hands-On Spanish Travel, an educational travel company designed to create
cultural awareness and acceptance of the Hispanic community.
I hope you enjoy your visit. If you have any questions
or comments, please send me an email.
Student obtained 2nd place in New College's Reseach Expo!
Two of my students, Lisa Tsosie and Spencer Pearson, participated in the New College’s Undergraduate Student Research and Creative Projects Expo 2013 (ASU). They both did a great job presenting their research posters. Lisa presented her work on Facebully (identification of cyberbullying in Facebook) and Spencer presented his work on index-based similarity joins. Lisa obtained the second prize in the Mathematical and Natural Sciences category. Congratulations Lisa!
We received an Amazon Educational Grant!
We have been recently selected to receive an AWS in Education Coursework grant! This Amazon grant will play a key role in our efforts to integrate highly distributed technologies, particularly the MapReduce framework and Big Data analysis using Hadoop, into the Applied Computing curricula at ASU-West. The award will provide our students with AWS credits and will be used in our advanced databases and distributed systems courses (Spring and Fall 2013).
ASU News video highlights research with one of my undergraduate students
An ASU News video highlights the research work performed by undergraduate students and ASU faculty under the NCUIRE (New College Undergraduate Inquiry and Research Experiences) program. NCUIRE enables a close interaction between students and faculty members at ASU-West to perform high-quality research. The video highlights, among others, the work with one of my undergraduate students (Spencer Pearson). You can watch the video here.
Faculty Doctoral Mentoring Institute
On March 4th, 2013, I participated in the 6th Arizona MGE@MSA Faculty Doctoral Mentoring Institute held at the Arizona State University Tempe Campus. This institute was a great opportunity to discuss and learn more about how we can increase the participation and retention of underrepresented groups in higher education. I particularly enjoyed meeting and talking with Richard Tapia, a distinguished professor who has inspired many African-American, Native American and Latino/Latina students to pursue careers in computing and mathematics.
Collaborative Research Project: ASU - HP Labs
I recently started a collaborative project with Rares Vernica from HP Labs. In this project (“MapReduce-based Parallel Face Clustering”), we are studying techniques to efficiently support distributed similarity-aware operators that use face-similarity functions on complex face-feature vectors.
Undergraduate research proposal funded
Our undergraduate research proposal entitled "FaceBully: Identifying Cyberbullying Behavior in Facebook” has been awarded funding from the Western Alliance to Expand Student Opportunities (WAESO). I look forward to keep collaborating in this project with my student Lisa Tsosie during Spring 2013.
Paper accepted in the VLDB Journal!
Our paper "Similarity Queries: Their Conceptual Evaluation, Transformations, and Processing", Y.N. Silva, W.G. Aref, P.-A. Larson, S. Pearson and M.H. Ali, has been accepted in the VLDB Journal. In this paper we focus on the study of similarity queries that contain one or multiple first-class similarity database operators (Similarity Selection, Similarity Join, and Similarity Group-by). We introduce a comprehensive conceptual evaluation model for similarity queries, and present a rich set of transformation rules to extend cost-based query optimization to the case of similarity queries. Congratulations to all my co-authors!
We received an Amazon Research Grant!
Our proposal "Similarity Join Operators for Cloud Systems" recently received an Amazon Web Services (AWS) Research grant. We look forward to keep using Amazon’s great cloud services in our research work!

Finished Summer '09 Internship at Microsoft Research
I spent the summer '09 at the Microsoft Research (MSR) lab in Redmond, WA where I had the honor and pleasure to work with Paul Larson and Jingren Zhou. My research task during this summer involved enhancing the optimizer of a massive data distributed management system to make efficient use of common query sub-expressions.
Being at Microsoft Research was also a great opportunity to interact with its great researchers; I especially enjoyed the discussions with different researchers of the Database and Data Management, Exploration and Mining groups. It was also a great experience to present the research work I have done at Purdue to MSR researchers and the results of my summer work to both the MSR researchers and the SQL Server team.
Together with my wife and two sons, I explored the beautiful parks and beaches during the weekends. We especially enjoyed exploring the rainforests at the Olympic Peninsula.

Finished Summer '08 Internship at IBM Research Almaden Center
My summer '08 was full of great challenges and a lot of fun working with the Information Management Group at the IBM Almaden Research Center (IBM ARC), San Jose, CA where I had the pleasure and honor to work with Guy Lohman and Sandeep Tata. My work at IBM ARC involved designing and prototyping a data management system that can inherently support unstructured and structured data.
This was a great opportunity to meet several other researchers at IBM Research and learn about other exciting projects currently in development at IBM. Lee Ann, Gabriel and I took advantage of the weekends to visit the surrounding national parks and beautiful coastal cities, and to spend time with new great friends.
Completed 'Mini-MBA' Program at The Krannert School of Management, May 2008
The beginning of my summer was packed with interesting business related classes and hands-on activities having been selected by the Computer Science Department to participate in the Applied Management Principles Program at the Krannert School of Management.
This executive education program is designed for select doctoral students in science and engineering and industry participants. We received instruction in interesting topics like accounting, human resource management, financial management, marketing, strategic management and entrepreneurship.
