Ajith Chrysantha Stephen Perera, JP, CChem., FRSC (born 29 February 1956) is a Chartered Chemist by profession, a scholar, a former senior manager in industry, a qualified training instructor, also a former test-match-panel cricket umpire.The international admiration Perera has won and the national recognition he has gained have come through his achievements, acquired both in Sri Lanka and in England in different fields: cricket, analytical chemistry and quality assurance, in all of which he is academically and professionally well qualified and widely experienced.Almost on the eve of umpiring his first cricket test match in Colombo, Sri Lanka vs New Zealand, a large wayside tree crashed on and straddled his moving car, killing his chauffeur and leaving him instantaneously a paraplegic for life.Undeterred by this personal adversity, he has bounced back to serve humanity.
Today he is a writer, speaker, author and a disability rights activist - as a fervent advocate for inclusion of all people by design - most importantly as a widely experienced and highly competent accessibility adviser and an accessor, befittingly recognised by three learned societies and several reputed bodies overseas.He is the founder and, as of 1 October 2019, holds the honorary position of Chief Executive / Secretary-General of Idiriya, a registered, not-for-profit humanitarian service organisation in Sri Lanka.
