Sacred and Secular, Mourning and Celebrating: Analyzing Ḥalutzi Burial Culture via Cemetery Gravestones

October 22, 2026

Talk, Israeli Association for the Study of Religion, Tel Hai, Israel

Cemeteries are sacred communal spaces. In them, communities memorialize their dead with monuments and inscriptions, messages to the future carved in stone. The text and attributes of the gravestone reflect what the remembering community felt was worthy of preservation, a window into attitudes about the person specifically and death in general. The Second and Third Aliyah ḥalutzi period in the Land of Israel (1910-1923) was a landmark period of social change and innovation. New communal attitudes emerged and communities dealt with social troubles, including difficult lives that included young death from illness, violence, and suicide. We examine ḥalutzi period burial culture generally and attitude toward suicide specifically through the lens of 163 gravestones, including 31 reported cases of suicide. Most of the burials are in the Galilee, a center of communal agricultural life then. We analyze the content and sentiment of the gravestones, paying special attention to the subset of gravestones from suicide cases. Through the set, we also explore trends, including use of sacred language, memorialization of family and social group, recording cause of death, and sentiments expressed through epitaphs. Comparing the ḥalutzi era epitaphs with those from other Jewish communities, we find that ḥalutzi era gravestones showed a modesty of language and style and a tendency to simply describe life as lived with little embellishment or poetry.

Using Generative AI to Analyze and Understand Cemetery Gravestones and Burial Culture

October 20, 2026

Talk, 42nd Conference of the Association for Israel Studies (2026), Ramat Gan, Israel

Cemeteries are places where we remember the dead through physical memorials, religious rituals, and national ceremonies. As places of memory, they figure prominently in the national conscious on days of national remembrance. Preserving and studying these spaces is vital for understanding Israeli and Jewish burial culture. In 2019, we launched CemoMemo, an online system to digitally document cemeteries in Israel and abroad, enabling historical research and virtual visits and creating a digital snapshot safe from physical damage or access restrictions due to war or pandemic.

Canonical Digests for Compressed Archives

August 25, 2026

Talk, 2026 ACM Symposium on Document Engineering (DocEng), Fribourg, Switzerland

Saed Kezel and I presented a new technique to create canonical digests for compressed archives that is independent of compression algorithm and archive format. The digests enable off-line and remote comparison of compressed archives with differing metadata fields. They can help with tasks such as download deduplication, content distribution, and compression flexibility.

Privacy preserving parking

March 01, 2019

Talk, Privacy in data management systems: Day of Study in Memory of Dr. Anat Aharoni, Haifa University, Haifa, Israel

A talk about privacy preservation in municipal parking systems. I presented the scope of the problem and offered a privacy preserving architecture that will make it possible to park on the street using cellular based parking while preserving the level of privacy from classical parking technologies (e.g. parking meters).

Creating Continuity in Software Engineering Capstone Projects

February 01, 2016

Conference proceedings talk, 4th Kinneret Conference on Software Engineering Education, Kinneret College on the Sea of Galilee, Israel

I talked about Kinneret Software Engineering’s model for creating and maintaining quality in capstone projects. I brought examples from successful projects and shared the stage with a repeat capstone project from Rafael Advanced Defense Systems.

Getting Authorization Right for Android Apps

June 30, 2015

Conference proceedings talk, ILAIS 2015, Ono Academic College, Kiryat Ono, Israel

I presented the Authzoid Android secure authorization system I developed with Karthikeyan Bhargavan. I showed how Android file sharing includes many security vulnerabilities. Authzoid shows a path forward for improving security and privacy in apps that share files.
