From Ohr Chaim’s website:
Harav Yitzchok Silber shlit”a has been serving since 2010 as the head of our distinctive Kollel, which is located in our shul. Members of this Kollel are exceptional avreichim, primarily, select chassidishe residents of Monsey. Harav Silber, in addition to being a distinguished talmid chochom, is also a renowned personality of great influence in Torah and Haskafah. Harav Silber has over the years attracted many talmidim and admirers and is proficient in providing counseling on spiritual matters as well as in the field of education. The Rav shlit”a is a widely recognized expert in the research of various challenging Torah topics and a sough-after lecturer as well. Over the years the Rav has authored many well accepted works of Torah articles and essays which attracted much interest, among them his widely celebrated sefer “Shaos Shavos Behalcha” on the subject of Zemanim. This sefer has been commended by the most eminent gedolim in Halacha of our generation.
