He spent the better part of three years researching the halachic acceptability of identifying and re-instituting the mitzvah of tekhelet – culminating in his work “Lulaot Tekhelet
” which is heralded as a major breakthrough into the Chareidi community. His lectures and shiurim on the subject focus primarily on the theoretical and Talmudic aspects of the re-identification of the coveted dye. He presently lives in Neve Yaakov, Jerusalem.

Rav Tavger is the Rabbinical advisor of the Ptil Tekhelet Association
. His involvement with tekhelet began in his kollel studies during which time he published his first work on tekhelet in the Journal Moria, with the blessing of HaRav Hagaon Shmuel Auerbach S”hlita. Further in-depth research of the subject led to the publication of his seminal work “Klil Tekhelet”. In 1988, his research culminated in the first ever dyeing of tekhelet for the mitzvah of tzitzit from the Murex trunculus since its disappearance 1300 years prior. Rav Tavger then joined the founders of Ptil Tekhelet to become the organization’s guiding light.
In addition to his efforts with the Ptil Tekhelet Organization, Rav Tavger has been teaching in Moscow in Yeshivat Torat Chaim founded by HaRav Hagaon Moshe Soloveitchik ZT”L and currently under the auspices of HaRav Hagaon Aharon Leib Steinman S”hlita. Rav Tavger resides in Kiryat Sefer with his wife Miriam and their eleven children.
