High-redshift supernovae are an important tool for measuring the cosmological parameters Omega_0 , Lambda , and Omega_k that describe our expanding universe. We have shown that the rare, random, and transient supernovae can be systematically detected and studied at high redshifts. So far, we have discovered and studied over 28 supernovae at redshifts z = 0.35 -- 0.85, and identified most of these as Type Ia supernovae. We present our measurements of cosmological parameters and discuss other cosmological implications derived from the spectra and multi-band light curves of our supernovae.
