'''Louis''' is a solid-state [[physicist]] from India. His hypotheses about the [[red rain in Kerala|"red rain" phenomenon in Kerala]] have attracted controversy. In April 2008, he published a paper in which he hypothesised that samples of particles from the "blood-coloured" rain that fell in his state of [[Kerala]], India in the summer of 2001 were the result of a comet disintegrating in the upper atmosphere which comprised mainly [[microbe]]s from outer space.<ref name="L&K 2006">{{cite journal |last1=Louis |first1=Godfrey |last2=Kumar |first2=A.

Since October 2006 Louis has been at Department of Physics, [[Cochin University of Science and Technology]] (CUSAT) in [[Kochi, India|Kochi]], Kerala.

In August 2010 Louis and his collaborators presented a paper at the SPIE astrobiology conference held in San Diego, USA, claiming that the red rain cells develop internal daughter cells and multiply when exposed to extreme temperature of 121 °C in an autoclave for two hours, and that the fluorescent behavior of the red cells is similar to the extended red emission observed in the [[Red Rectangle nebula]].<ref name= spie2010_1 >{{cite journal |last1=Gangappa |first1=Rajkumar |last2=Wickramasinghe |first2=Chandra |last3=Wainwright |first3=Milton |last4=Kumar |first4=A.
